U.S.-South Korea Relations
.
Summary
Overview
South Korea (known officially as the Republic of Korea, or ROK) is one of the United States’
most important strategic and economic partners in Asia,
and for the past five years relations between the two countries (known officially as the Republic
of Korea, or ROK) have been arguably at their best and since 2009 relations between the two
countries arguably have been at their most robust state in decades. Members of Congress tend
to to
be interested in South Korea-related issues for a number of reasons. First, the United States and
South Korea have been treaty allies since the early 1950s. The United States is committed to helping
helping South Korea defend itself, particularly against any aggression from North Korea.
Approximately 28,500 U.S.
troops are based in the ROK and South Korea is included under the
U.S. “nuclear umbrella.”
Second, Washington and Seoul cooperate over how to deal within addressing the challenges
posed by North
Korea. Third, the two countries’ economies are closely entwined and are joined
by the Korea-U.S.
Free Trade Agreement (KORUS FTA). South Korea is the United States’ sixth-largest trading
partner. Thesixthlargest trading partner and the United States is South Korea’s second-largest trading partner. In late 2013 and early
2014,
South Korea tookhas taken the first steps toward possible entry into the U.S.-led Trans-Pacific
Partnership (TPP) free trade agreement negotiations.
Strategic Cooperation and the U.S.-ROK Alliance
Dealing with North Korea is the dominant strategic elementconcern of the U.S.-South Korean
relationship. Under South Korean President Park Geun-hye, Seoul and Washington have
maintained tight coordination over North Korea policy, forging in effectfollowing a joint approach that
contains elements of pressure and engagement. The Obama Administration has supported Park’s
“trustpolitik” approach, under which Seoul has proposed some modest confidence-building
measures with and humanitarian assistance to Pyongyang in order to build trust between the two
sides. Thus far, Park has linked large-scale aid to progress in the denuclearization of North Korea,
the United States’ top priority. An issue for the Obama Administration and Congress is to what
extent they will support—or, not oppose—Park’s possible inter-Korean initiatives if they expand
further. In early 2014, Park launched a campaign to lay the groundwork for an eventual
reunification of the two Koreas, which she has referred to as a “bonanza” that will benefit both
Koreas economically contains
elements of pressure and engagement. In response to Pyongyang’s perceived intransigence and
provocative behavior, Washington and Seoul have placed significant emphasis on the harder
elements of their approach. Some critics say that the Obama Administration’s policy applies
insufficient pressure on North Korea to change its behavior, while others argue that it provides
insufficient incentives. The Obama Administration has supported Park’s proposals for confidencebuilding measures with and humanitarian assistance to Pyongyang. She has linked larger-scale aid
to progress in the denuclearization of North Korea, the United States’ top priority. Thus far, North
Korea generally has resisted Park’s outreach.
Since 2009, the United States and South Korea have accelerated steps to reform the U.S.-ROK
alliance. Washington and Seoul have initiated plans to relocate U.S. troops on the Korean
Peninsula and
boost ROK defense capabilities. Some Members of Congress have criticized the
cost of the relocation, and
Park and her predecessor have slowed the planned defense budget increases.
Provocations from
North Korea have propelled more integrated bilateral planning for responding
to possible
contingencies, for instance by adopting policies to respond more swiftly and forcefully
to attacks
and by discussing improvements to the two countries’ respective missile defense systems. In
January 2014, the United States and South Korea reached a new five-year Special Measures
Agreement (SMA), under which Seoul will raise its host nation support payments for U.S. forces
in Korea by 6%, to around $870 million per year. During President Obama’s April 2014 visit to
Seoul,
systems. In a related development, in 2014 the United States and South Korea agreed to delay for
the second time a 2007 agreement to
transfer wartime operational control (Opcon) from U.S. to
ROK forces later this decade.
On broad strategic matters in East Asia, while South Korean and U.S. perspectives overlap, there
are areas of significant differences. For instance, South Korea often hesitates to take steps that
antagonize China and has shown mistrust of Japan’s efforts to expand its military capabilities.

Nuclear Cooperation Agreement
In 2013 the Obama and Park governments agreed to a two-year extension of a bilateral civilian
nuclear agreement, which now will expire in March 2016. The House and the Senate unanimously
unanimously passed the extension, which is considered a temporary solution to avoid any
disruption to nuclear
energy trade and provide more time for negotiations to continue. South Korea reportedly has
requested that the new agreement include provisions that would allow for future uranium
enrichment and reprocessing in South Korea. The Obama Administration has resisted this change,
which would pose challenges for U.S. non-proliferation policy.

Korea sought expanded permission for fuel cycle activities, but the Obama Administration has
resisted this change, which would pose challenges for U.S. non-proliferation policy. Both sides
have stressed the importance of continuing the close civilian nuclear energy partnership between
the two countries. The two countries have concluded negotiations on the text of a new agreement,
which is expected to be signed in June 2015. This would be followed by its transmittal to
Congress for a required review period before the current agreement expires.

Developments in the First Half of 2014
Since late 2008, relations between the United States and South Korea (known officially as the
Republic of Korea, or ROK) arguably have been at their best state since the formation of the
U.S.-ROK alliance in 1953. Lee and Park both spoke before joint sessions of Congress, in
October 2011 and May 2013, respectively. Although the overall U.S.-South Korean relationship
has remained healthy under Park, she has hinted at policy moves that could test bilateral ties,
particularly with respect to North Korea and the renewal of a U.S.-ROK civilian nuclear
cooperation agreement.

President Obama’s April 2014 Trip to South Korea
In what analysts generally regarded as a successful visit, President Obama traveled to South
Korea for a day in late April as part of a week-long trip to Asia that also included Japan,
Malaysia, and the Philippines. During the President’s visit, the United States and South Korea
announced an agreement to delay the transfer of wartime operational control (OPCON) from U.S.
to South Korean commanders that was slated to take place in 2015, citing the more dangerous
North Korean threat and needed improvements to military interoperability. The two countries’
joint statement declared, among other items, a mutual recognition of the need for improved
trilateral information sharing among the United States, South Korea, and Japan to cope with the
North Korean threat.1 President Obama and President Park also discussed implementation of the

U.S.-South Korea Relations
South Korea-U.S. Free Trade Agreement (KORUS FTA), Seoul’s interest in joining the TransPacific Partnership (TPP), diplomatic strategy for potential nuclear negotiations with North
Korea, and the contentious history issues convulsing Japan-ROK relations.
Sewol Ferry Sinking
The deaths of nearly 300 passengers—mostly high school students—in an April 16 sinking of the
Sewol ferry cast a pall over South Korea during the President’s visit. The accident has become a
national trauma. The Park government has been criticized for rescuers’ allegedly slower-thannecessary response to distress calls, and the accident has prompted South Koreans to ask
questions about how well government agencies have enforced safety regulations, the relationship
between government regulators and the industries they oversee, as well as whether companies
have put profits ahead of safety. Government prosecutors have brought criminal charges,
including accidental homicide, against the captain and members of the crew. In some polls,
President Park’s approval ratings and political standing have fallen by more than 10%, down to
the 40%-50% range, since the accident.
Cooperation over North Korea Policy2
Dealing with North Korea is the dominant strategic element of the U.S.-South Korean
relationship. Park has said that her preferred policy toward North Korea “entail[s] assuming a
tough line against North Korea sometimes and a flexible policy open to negotiations other times.”
Some of the cooperative elements of Park’s approach toward North Korea could conflict with
U.S. policy, due to an inherent tension that exists in the two countries’ views of Pyongyang: the
United States’ predominant concern is North Korea’s weapons of mass destruction (WMD)
programs, but the nuclear and long-range missile issues often competes with other issues, like
promoting unification, for the top slot on South Korea’s list of priorities. Because inter-Korean
relations have been so poor since 2008, such potential contradictions between U.S. and South
Korean interests have not been exposed.
Both Seoul and Washington have emphasized deterrence in the face of a series of hostile actions
by North Korea, including Pyongyang’s February 2013 nuclear test (its third since 2006), signs of
further progress in North Korea’s missile capabilities, and Pyongyang’s firing of hundreds of
short-range rockets in March and April 2014. President Park has pledged to retaliate militarily if
North Korea attacks the South, as it did in 2010, and over the past year Seoul and Washington
ironed out a new counter-provocation plan. The latter was developed to adapt both to the new
threats envisioned from North Korea and to the South Korean government’s new willingness to
retaliate.
Since she began campaigning for the presidency, Park has called for creating a “new era” on the
Korean Peninsula by building trust between North and South Korea. However, she has stated that

U.S.-South Korea Relations
a nuclear North Korea “can never be accepted” and that trust-building with Pyongyang will be
impossible if North Korea cannot keep the agreements made with South Korea and the
international community. Thus, her “trustpolitik,” which the Obama Administration has
supported, has combined a mixture of tactics, employing “a tough line” in response to
Pyongyang’s military provocations and “a flexible policy open to negotiations” when North
Korea’s behavior is more cooperative.
An issue for the Obama Administration and Congress is to what extent they will support—or not
oppose—Park’s proposed inter-Korean initiatives. For instance, legislative efforts in Congress to
expand U.S. sanctions against North Korea, such as H.R. 1771, the North Korea Sanctions
Enforcement Act, could conflict with some of Park’s initiatives. Thus far, the Obama
Administration appears comfortable letting Seoul take the lead in trying to encourage more
cooperative behavior from Pyongyang. Park has delinked Seoul’s humanitarian assistance to
North Korea from other diplomatic developments.
Since early 2014, Park has launched a campaign to lay the groundwork for an eventual
reunification of the two Koreas, which she has referred to as a “bonanza” that will benefit both
Koreas economically. Among other items, she has proposed to Pyongyang that the two Koreas
hold regular reunions for families separated since the Korean War ended in 1953 and has held out
the prospect of South Korean investments in North Korean infrastructure projects. She appears to
have linked large-scale investments to a North Korean decision to “choose the path of
denuclearization.”3 North Korea has rejected Park’s offer to take preliminary steps toward reintegrating the two Koreas. (For more on cooperation over North Korea, see the “North Korea in
U.S.-ROK relations” section.)
Nuclear Energy Cooperation Agreement
In April 2013, the United States and South Korea announced that they had agreed to a two-year
extension of the existing bilateral civilian nuclear cooperation agreement, also known as a 123
agreement, which was due to expire in March 2014.4 Legislation to authorize the two-year
extension was passed unanimously by both the House and Senate and signed into law by
President Obama on February 12, 2014 (P.L. 113-81).5 For years, talks between South Korea and
the United States were not able to resolve disagreement over how to treat fuel-making
technologies in a renewed accord, and therefore the two countries decided to allow for more
negotiating time. The two-year extension is considered a temporary solution to avoid any
disruption to nuclear trade. A lapse could have affected exports of U.S. nuclear materials and
reactor components to Korea, and could potentially affect ongoing construction of South Korean
reactors in the United Arab Emirates, for which U.S. companies are providing components and
services.

U.S.-South Korea Relations
One point of disagreement in the renewal process is whether South Korea will press the United
States to include a provision that would allow for the reprocessing of its spent fuel. The South
Korean government is reportedly also seeking confirmation in the renewal agreement of its right
to enrichment technology. The current U.S.-Korea nuclear cooperation agreement, as with other
standard agreements,6 requires U.S. permission before South Korea can reprocess U.S.-origin
spent fuel, including spent fuel from South Korea’s U.S.-designed reactors.7 The issue has
become a sensitive one for many South Korean officials and politicians, who see it as a matter of
national sovereignty. The United States has been reluctant to grant such permission due to
concerns over the impact on negotiations with North Korea and on the nonproliferation regime
overall. Through reprocessing, spent fuel can be used to make reactor fuel or to acquire
plutonium for weapons. For many years, the United States and South Korea have worked on joint
research and development projects to address spent fuel disposition, including joint research on
pyro-processing, a type of spent fuel reprocessing. In October 2010, the two countries began a 10year, three-part joint research project on pyro-processing that includes joint research and
development at Idaho National Laboratory, development of international safeguards for this
technology, economic viability studies, and other advanced nuclear research including
alternatives to pyro-processing for spent fuel disposal.8 (For more on the negotiations and the
debate over U.S.-ROK civilian nuclear cooperation, see the “Nuclear Energy and NonProliferation Cooperation” section below.)
South Korea Expresses Interest in TPP
In the fall of 2013, after months of speculation, the South Korean government signaled its
“interest” in joining the twelve-nation Trans-Pacific Partnership (TPP) free trade agreement
talks.9 The economic size and strategic importance of TPP would expand significantly if South
Korea—East Asia’s third-largest economy—enters the negotiations.10 One of Park’s top policy
agendas is reviving the country’s economy. To this end, her government has initiated a trade
strategy of entering into more FTAs, thereby making South Korea into a “linchpin” of accelerated
economic integration.11 South Korea is negotiating a number of FTAs, including a bilateral
agreement with China as well as a trilateral agreement with China and Japan. South Korea also
recently concluded bilateral FTA negotiations with Australia and Canada.

Under the 1978 Nuclear Nonproliferation Act, consent rights apply to material originating in the U.S. or material that
has been fabricated into fuel or irradiated in a reactor with U.S. technology. The majority of South Korea’s spent fuel

While expanding the size of the potential agreement, South Korea’s entry into TPP would be expected to have a
smaller impact on U.S.-South Korea trade flows, because of the existing bilateral U.S.-South Korea free trade
agreement (KORUS).

U.S.-South Korea Relations
The Obama Administration has “welcomed” Korea’s interest in joining the talks, though United
States Trade Representative (USTR) officials also have indicated they will place priority on
concluding an agreement with the existing members before agreeing to the entry of any new
countries. The current TPP countries must reach unanimous agreement on South Korea’s entry
before Seoul can join, and in December 2013 Korea began holding preliminary consultations with
TPP members.
The next formal step for South Korea to enter the TPP would be for the South Korean
government to formally announce that it is seeking to participate. The United States may require
some preliminary commitments from Seoul before it agrees to South Korea’s participation in the
negotiations. South Korea’s willingness and ability to resolve remaining issues with the
implementation of the KORUS FTA are among such measures.12 For example, U.S. exporters
have claimed the agreement’s effectiveness has been diminished by South Korean customs
authorities requiring allegedly excessive documentation to certify rules of origin of imports of
U.S. products. U.S. officials have also argued that a South Korean tax credit/tax penalty program
for car purchases discriminates against imports of U.S.-made cars. U.S. officials reportedly also
have been discussing with South Korea issues that would be included in the TPP but are not part
of the KORUS FTA, such as state-owned enterprises and regulatory coherence, to see if South
Korea would be prepared to make commitments in these areas. If Seoul officially seeks to
participate in the negotiations and reaches agreements with the 12 members over the terms of its
entry, they would officially invite South Korea to join and also initiate their domestic notification
procedures. In the case of the United States, this latter process would involve notifying Congress
of an intention to enter into FTA negotiations with South Korea after a period of 90 days.
Ultimately, Congress must approve implementing legislation if a completed TPP agreement—
with or without South Korea—is to apply to the United States. Additionally, during the TPP
negotiating process, Congress has a formal and informal role in influencing U.S. negotiating
positions, which can include the process of granting new trade promotion authority (TPA) to the
President. TPA, which expired in 2007, is the authority that Congress gives to the President to
negotiate trade agreements that would receive expedited legislative consideration. In January
2014, legislation to renew TPA was introduced in the House (H.R. 3830) and in the Senate (S.
1900).13 (For more on U.S.-South Korean economic relations, see the “Economic Relations”
section.)
South Korea-Japan Relations
South Korea’s relations with Japan continued to worsen in the first half of 2014, a development
that drew considerable attention from U.S. policy makers and Members of Congress who met
with officials from both countries. A poor relationship between Seoul and Tokyo jeopardizes U.S.
interests by complicating more robust trilateral cooperation over North Korea policy and
discussions about regional trends such as China’s rise. Tense relations also complicate Japan’s

remarks, President Obama said, “I discussed this [KORUS implementation] with President Park last night. We both
agreed that these are issues we can work through together. And given South Korea’s interest in the Trans-Pacific
Partnership, fully implementing KORUS also is the single most important step that South Korea can take now to show
that it’s prepared to eventually meet the high standards of TPP.”

U.S.-South Korea Relations
desire to expand its military and diplomatic influence, goals the Obama Administration generally
supports, as well as the creation of an integrated U.S.-Japan-South Korea missile defense system.
South Korea’s relations with Japan were a major topic of President Obama’s April visits to Seoul
and Tokyo, and they took center stage in late March, when President Obama orchestrated the first
official meeting between Park and her Japanese counterpart, Prime Minister Shinzo Abe, on the
sidelines of the Nuclear Security Summit. The three leaders discussed cooperation over North
Korea policy.
In South Korea leaders have objected to a series of statements and actions by Abe and his Cabinet
officials that many have interpreted as denying or even glorifying Imperial Japan’s aggression in
the early 20th century. Seoul has maintained that it would have difficulty holding a summit, or
improving relations, unless Japan adopts a “correct understanding” of history. These sentiments
hardened in December 2013 when Abe visited the Yasukuni Shrine, which houses the spirits of
Japanese soldiers who have died during war, including several individuals who were convicted as
Class A war criminals after World War II.
Another major focus of South Korean grievances is a contention that Japan has inadequately
acknowledged and addressed the suffering of the World War II “comfort women,” women who
were forced to provide sexual services to Japanese soldiers during Imperial Japan’s conquest and
colonization of several Asian countries in the 1930s and 1940s, including Korea. For a brief
window in April, it seemed that the two governments were trying to get relations back on track by
opening a diplomatic channel to discuss the “comfort women” issue. These efforts faltered,
however, when the Abe government released a study in June that examined the “Kono
Statement,” a 1993 apology by then-Chief Cabinet Secretary Yohei Kono that acknowledged the
Japanese military’s role in coercing women into the brothel system. The panel that conducted the
study, carried out in response to a request by a Diet member of a far-right opposition party,
concluded that the statement had been crafted in consultation with Seoul, implying that the
document was not based solely on historical evidence. The Abe government has pledged that it
stands by the Kono Statement, but critics claim that the study discredits the apology and gives
further proof of Tokyo’s (and specifically Abe’s) revisionist aims. South Korea’s Foreign Ministry
called the study “meaningless and unnecessary.”
The U.S. House of Representatives has taken an interest in the comfort women issue and has
introduced two resolutions, one in 2006 and one in 2007. In the 109th Congress, H.Res. 759 was
passed by the House International Relations Committee on September 13, 2006, but was not
voted on by the full House. In the 110th Congress, H.Res. 121, with 167 co-sponsors, was passed
in the House on July 30, 2007, by voice vote. This resolution expresses the sense of the House
that Japan should “formally acknowledge, apologize, and accept historical responsibility in a
clear and unequivocal manner” for its abuses of the comfort women. The text of the resolution
calls the system “unprecedented in its cruelty” and “one of the largest cases of human trafficking
in the 20th century,” asserts that some Japanese textbooks attempt to downplay this and other war
crimes, and states that some Japanese officials have tried to dilute the Kono Statement. In the
113th Congress, the 2014 Consolidated Appropriations Act (P.L. 113-76, H.R. 3547) indirectly
referred to this resolution. P.L. 113-76’s conference committee issued a Joint Explanatory

U.S.-South Korea Relations
State of the Alliance
Since 2009, the United States and South Korea have accelerated steps to transform their alliance,
broadening it from its primary purpose of defending against a North Korean attack to a regional
and even global partnership. Joint statements issued from a series of high-level meetings
emphasized the commitment to modernize and expand the alliance while reaffirming the
maintenance of current U.S. troop levels on the peninsula and the U.S. security guarantee to
protect South Korea. Spurred by violent attacks from North Korea in 2010, the alliance partners
agreed on a “Counter-Provocation Plan” and then sharpened the agreement by developing a
“Tailored Deterrence Strategy against North Korean Nuclear and Other WMD Threats.” A highlevel joint statement in October 2013 committed both sides to improving their missile defense
systems.
Despite these indicators of strength, the alliance faces a host of challenges in the months and
years ahead. The political atmospherics of the alliance have been positive, but the conservative
Park and Lee governments have slowed the defense budget increases planned under the earlier,
progressive Roh Moo-hyun Administration (2003-2008). The two countries also must resolve
disputes related to the realignment of U.S. forces within Korea, a process that Congress has
followed closely because of concerns about the cost.
The 2007 agreement to transfer wartime operational control (Opcon) from U.S. to ROK forces by
2015 has resurfaced as a point of controversy. At the request of South Korea, the United States
has agreed to review the timing of the Opcon transfer and will reportedly delay the transfer to the
2020s, after South Korea improves military capabilities in specified domains.14 The planned
realignment of all U.S. forces from bases near the de-militarized zone (DMZ) border with North
Korea to bases farther south is making progress, but one aspect of the plan is under review. The
commander of U.S. Forces Korea (USFK) has indicated that some “residual” staff may continue
to fulfill the so-called “tripwire” function of U.S. forces stationed near the DMZ.15 South Korean
defense officials denied that any U.S. troops would remain “north of Seoul.”16 (For more on
alliance issues, including congressional actions, see the “Security Relations and the U.S.-ROK
Alliance” section.)
Background on U.S.-South Korea Relations
Overview
While the U.S.-South Korea relationship is highly complex and multifaceted, five factors
arguably drive the scope and state of relations between the two allies:
•
the challenges posed by North Korea, particularly its weapons of mass
destruction programs and perceptions in Washington and Seoul of whether the

U.S.-South Korea Relations
Kim Jong-un regime poses a threat, through its belligerence and/or the risk of its
collapse;
•
the growing desire of South Korean leaders to use the country’s middle power
status to play a larger regional and, more recently, global role;
•
China’s rising influence in Northeast Asia, which has become an increasingly
integral consideration in many aspects of U.S.-South Korea strategic and
economic policymaking;
•
South Korea’s transformation into one of the world’s leading economies—with a
strong export-oriented industrial base—which has led to an expansion of trade
disputes and helped drive the two countries’ decision to sign a free trade
agreement; and
•
South Korea’s continued democratization, which has raised the importance of
public opinion in Seoul’s foreign policy.
Additionally, while people-to-people ties generally do not directly affect matters of “high”
politics in bilateral relations, the presence of over 1.2 million Korean Americans and the hundreds
of thousands of trips taken annually between the two countries has helped cement the two
countries together.
Members of Congress tend be interested in South Korea-related issues because of bilateral
cooperation over North Korea, a desire to oversee the management of the U.S.-South Korea
alliance, South Korea’s growing importance on various global issues, deep bilateral economic
ties, and the interests of many Korean Americans. The 112th Congress held over 15 hearings
directly related to South and North Korea.
Large majorities of South Koreans say they value the U.S.-ROK alliance and have positive
opinions of the United States. However, many South Koreans are resentful of U.S. influence and
chafe when they feel their leaders offer too many concessions to the United States. South Koreans
also tend to be wary of being drawn into U.S. policies that antagonize China. Although many of
these concerns are widely held in South Korea, they are particularly articulated by Korea’s
progressive groups, who have opposed much of Park and Lee’s policy agenda and their governing
styles.
Historical Background
The United States and South Korea have been allies since the United States intervened on the
Korean Peninsula in 1950 and fought to repel a North Korean takeover of South Korea. Over
33,000 U.S. troops were killed and over 100,000 were wounded during the three-year conflict. On
October 1, 1953, a little more than two months after the parties to the conflict signed an armistice
agreement, the United States and South Korea signed a Mutual Defense Treaty, which provides
that if either party is attacked by a third country, the other party will act to meet the common
danger. The United States maintains about 28,500 troops in the ROK to supplement the 650,000strong South Korean armed forces. South Korea deployed troops to support the U.S.-led military
campaign in Vietnam. South Korea subsequently has assisted U.S. deployments in other conflicts,
most recently by deploying over 3,000 troops to play a non-combat role in Iraq and over 300 noncombat troops to Afghanistan.

U.S.-South Korea Relations
Beginning in the 1960s, rapid economic growth propelled South Korea into the ranks of the
world’s largest industrialized countries. For nearly two decades, South Korea has been one of the
United States’ largest trading partners. Economic growth, coupled with South Korea’s
transformation in the late 1980s from a dictatorship to a democracy, also has helped transform the
ROK into a mid-level regional power that can influence U.S. policy in Northeast Asia,
particularly the United States’ approach toward North Korea.
North Korea in U.S.-ROK relations
North Korea Policy Coordination
Dealing with North Korea is the dominant strategic element of the U.S.-South Korean
relationship. South Korea’s growing economic, diplomatic, and military power has given Seoul a
much more direct and prominent role in Washington’s planning and thinking about how to deal
with Pyongyang. One indicator of South Korea’s centrality to diplomacy over North Korea is that
no successful round of the Six-Party nuclear talks has taken place when inter-Korean relations
have been poor.
The Joint “Strategic Patience” Approach
Since 2009, U.S.-South Korean collaboration over North Korea has been extremely close, after
several years in which the two countries frequently had competing visions of how to handle North
Korea. In effect, Washington and Seoul have adopted a joint approach toward North Korea, one
that largely has continued during Park’s tenure. In essence, the approach—which is often called
“strategic patience”—has four main components:
•
keeping the door open to Six-Party Talks over North Korea’s nuclear program but
refusing to re-start them without a North Korean assurance that it would take
“irreversible steps” to denuclearize;17
•
insisting that Six-Party Talks and/or U.S.-North Korean talks must be preceded
by North-South Korean talks on denuclearization and improvements in NorthSouth Korean relations;
•
gradually attempting to alter China’s strategic assessment of North Korea; and
•
responding to Pyongyang’s provocations by tightening sanctions against North
Korean entities and conducting a series of military exercises.
Strategic patience could be described as a passive-aggressive approach that effectively is a policy
of containing North Korea’s proliferation activities, rather than rolling back its nuclear program.
One drawback is that it has allowed Pyongyang to control the day-to-day situation. While
Washington and Seoul wait to react to Pyongyang’s moves, the criticism runs, North Korea has
continued to develop its uranium enrichment program, has often appeared to solidify support
from China, and has embarked on a propaganda offensive designed to shape the eventual
negotiating agenda to its benefit. Many of Park’s proposed initiatives with North Korea appear

U.S.-South Korea Relations
designed to rectify these perceived shortcomings. To date, however, North Korea’s actions since
her inauguration have not provided her government with an opportunity to apply her policies.
The joint U.S.-ROK approach has involved elements of both engagement and pressure.
Washington and Seoul have tended to reach out to North Korea during relatively quiescent
periods. In contrast, they have tended to emphasize pressure tactics during times of increased
tension with North Korea. These periods occurred repeatedly after Lee Myung-bak’s inauguration
in February 2008. Most notably, they included North Korean nuclear tests in May 2009 and
February 2013; North Korean long-range rocket launches in April 2009, April 2012, and
December 2012; the March 2010 sinking of a South Korean naval vessel, the Cheonan; and the
November 2010 North Korean artillery attack on the South Korean island of Yeonpyeong-do.18
The latter incident was North Korea’s first direct artillery attack on ROK territory since the 19501953 Korean War and served to harden South Korean attitudes toward North Korea. President
Lee reportedly stated that he wanted to order a retaliatory air strike, but the existing rules of
engagement—which he subsequently relaxed—and the existence of the U.S.-ROK military
alliance restrained him.19 Park Geun-hye has implied that South Korea’s military response, which
primarily consisted of launching about 80 shells at North Korea and holding large-scale exercises
with the United States, was insufficient.
Inter-Korean Relations and Park Geun-Hye’s “Trustpolitik”
Park’s statements on North Korea policy include elements of both conciliation and firmness, and
she has written that her approach would “entail assuming a tough line against North Korea
sometimes and a flexible policy open to negotiations other times.”20 On the one hand, Park has
called for creating a “new era” on the Korean Peninsula by building trust between North and
South Korea. To build trust, Park has indicated a desire to eventually:
•
resume North-South Korean dialogue and give “new momentum” to the SixParty talks over North Korea’s nuclear program;21
•
delink humanitarian assistance from overall diplomatic developments and make
such assistance more transparent than in the past;
•
ease or end the restrictions on South Korean commercial ties to North Korea that
the South Korean government imposed after the April 2010 sinking of the South
Korean naval vessel, the Cheonan;
•
restore cooperation with North Korea for South Koreans to participate in tours of
Mt. Kumgang and Kaesong city inside North Korea;
18
On Yeonpyeong-do, over 150 shells fired by North Korea killed four South Koreans (two Marines and two civilians),
wounded dozens, and destroyed or damaged scores of homes and other buildings. All 46 South Korean sailors on the
Cheonan died. A multinational team that investigated the sinking, led by South Korea, determined that the ship was
sunk by a North Korean submarine. The cause of the Cheonan’s sinking has become highly controversial in South
Korea. While most conservatives believe that North Korea was responsible for explosion, many who lean to the left
have criticized the investigation team as biased or argue that its methodology was flawed.

U.S.-South Korea Relations
•
internationalize and expand the Kaesong Industrial Complex, an industrial park
inside North Korea where over 100 South Korean companies employ over 40,000
North Koreans;
•
uphold the promises former President Roh Moo-hyun made in an October 2007
summit with former North Korean leader Kim Jong-il to provide large-scale
economic assistance and fund reconstruction projects;
•
explore the building of a transportation and energy network running through
North Korea to connect South Korea with China, Russia, and the rest of Eurasia;
and
•
meet with North Korean leader Kim Jong-un “if it helps to foster South-North
relations.”22
These policies are generally consistent with Park’s actions and words for over a decade; for
instance, in 2002 she visited Pyongyang and met with Kim Jong-il. As of early 2014, she has
delinked humanitarian assistance from other diplomatic developments, and has offered smallscale bilateral assistance and allowed South Korean non-governmental groups to operate in North
Korea. The Obama Administration has indicated its support for Park’s trustpolitik.23
On the other hand, Park also has long stated that a nuclear North Korea “can never be accepted”
and that building trust with Pyongyang will be impossible if it cannot keep the agreements made
with South Korea and the international community. Park has also said that South Korea will “no
longer tolerate” North Korean military attacks, that they will be met with an “immediate” South
Korean response, and that the need for South Korea to punish North Korean military aggression
“must be enforced more vigorously than in the past.”24 After North Korea’s successful December
2012 launch of a satellite (using long-range missile technology), February 2013 nuclear test,
partial closure of the inter-Korean industrial park near the city of Kaesong, and bellicose rhetoric,
Park emphasized the strength of the ROK-U.S. deterrence posture. Meanwhile, the United States
demonstrated its commitment to defend South Korea with unusually well-publicized practice
sorties by B-52 bombers, B-2 bombers, and F-22 fighters, among other measures.
It is not clear how the Park government will resolve the seeming contradiction between the
impulses of toughness and flexibility. A key question will be the extent to which her government
will continue to link progress on denuclearization—the United States’ top concern—to other
elements of South Korea’s approach toward North Korea. Likewise, an issue for the Obama
Administration and Members of Congress is to what extent they will support—or, not oppose—
any initiatives by Park to expand inter-Korean relations.

U.S.-South Korea Relations
Deterrence Issues
One factor that may influence U.S.-ROK cooperation on North Korea is Pyongyang’s apparent
progress in its missile and nuclear programs. North Korea’s February 2013 nuclear test, for
instance, triggered calls in South Korea for the United States to redeploy tactical nuclear weapons
in the ROK and for South Korea to develop its own nuclear weapons deterrent. To reassure South
Korea and Japan after North Korea’s test, President Obama personally reaffirmed the U.S.
security guarantee of both countries, including extended deterrence under the United States’ socalled “nuclear umbrella.” In early March 2013, Park stated that “provocations by the North will
be met by stronger counter-responses,” and the chief operations officer at South Korea’s Office of
the Joint Chiefs of Staff was widely quoted as saying that if South Korea is attacked, it will
“forcefully and decisively strike not only the origin of provocation and its supporting forces but
also its command leadership.”25 South Korean defense officials later clarified that “command
leadership” referred to mid-level military commanders who direct violent attacks and not North
Korean political leaders such as Kim Jong-un.
Since North Korea’s 2010 shelling of Yeonpyeong Island, South Korean leaders have shown a
greater willingness to countenance the use of force against North Korea. The Lee government
pushed the alliance to develop a new “proactive deterrence” approach that calls for a more
flexible posture to respond to future attacks, as opposed to the “total war” scenario that drove
much of USFK defense planning in the past. For instance, Lee pushed the United States to relax
restrictions on South Korean ballistic missiles (see the “U.S. Alliance and ROK Defense Reform
Plans” section below) and relaxed the rules of engagement to allow frontline commanders greater
freedom to respond to a North Korean attack without first asking permission from the military
chain of command.26 Such changes have made some analysts and planners more concerned about
the possibility that a small-scale North Korean provocation could escalate. U.S. defense officials
insist that the exceedingly close day-to-day coordination in the alliance ensures that U.S.-ROK
communication would be strong in the event of a new contingency. The 2013 “CounterProvocation Plan” was developed to adapt both to the new threats envisioned from North Korea
and to the South Korean government’s new attitudes about retaliation.
Security Relations and the U.S.-ROK Alliance
The United States and South Korea are allies under the 1953 Mutual Defense Treaty. Under the
agreement, U.S. military personnel have maintained a continuous presence on the Korean
Peninsula and are committed to help South Korea defend itself, particularly against any
aggression from the North. The United States maintains about 28,500 troops in the ROK. South
Korea is included under the U.S. “nuclear umbrella,” also known as “extended deterrence,” which
applies to other non-nuclear U.S. allies as well. A bilateral understanding between Washington
and Seoul gives U.S. forces the “strategic flexibility” to respond to contingencies outside the
peninsula, but under the condition that South Korea would have to consent to their deployment in
an East Asian conflict. In the past, issues surrounding U.S. troop deployments have been a
flashpoint for public disapproval of the military alliance, led by progressive political groups, but

U.S.-South Korea Relations
in recent years public support for the alliance has become broader and more resilient to incidents
involving U.S. bases and soldiers in South Korea.
Despite the strengths of the alliance, tensions periodically arise in the partnership. Some of these
involve typical alliance conflicts over burden sharing and cost overruns of ongoing realignment
initiatives. Others reflect sensitive sovereignty issues involving Seoul’s control over its own
military forces and desire to develop its own defense industry without dependence on American
equipment. And although the United States and South Korea share a common interest in repelling
any North Korea attack, views on the overall security landscape in Northeast Asia differ. Seoul
resists adopting positions that threaten or offend China, and distrusts Japan’s efforts to expand its
military capabilities.
Upgrades to the Alliance
Since 2009, the two sides have accelerated steps to transform the U.S.-ROK alliance, broadening
it from its primary purpose of defending against a North Korean attack to a regional and even
global partnership. At the same time, deadly provocations from North Korea have propelled more
integrated bilateral planning for responding to possible contingencies. In 2011, the allies adopted
a “proactive deterrence” policy to respond swiftly and forcefully to further provocations.
Increasingly advanced joint military exercises have reinforced the enhanced defense partnership.
In March 2013, U.S. officials disclosed that B-52 and B-2 bombers participated in exercises held
in South Korea, apparently making this announcement as a demonstration of the U.S.
commitment to extended deterrence, following a period of unusually hostile rhetoric from
Pyongyang.27 In 2012, the two sides held their second so-called “2+2” meeting between the U.S.
Secretaries of State and Defense and their South Korean counterparts. Among other policy areas,
the joint statement emphasized new initiatives on cybersecurity and missile defense, and the
United States committed to maintaining current troop levels in Korea.
In 2013, in addition to developing new counter-provocation and tailored deterrence strategies, the
two sides issued a high-level joint statement in October 2013 committing to improving their
respective ballistic missile defense (BMD) systems. The United States has urged South Korea to
develop advanced BMD capabilities that are more integrated with U.S. and allied BMD systems
in the region, as shown in the aforementioned joint statement issued during President Obama’s
April 2014 visit to Seoul. The Vice Chairman of the U.S. Joint Chiefs of Staff has explained that a
regional missile defense system would be more effective against North Korean missile launches
and would share the burden of defense among allies.28 However, Seoul has been resistant to the
concept of an integrated BMD system for several reasons: the desire, especially strong among
progressive Koreans, for more strategic autonomy; a reluctance to irritate China, which has
consistently voiced opposition to U.S. BMD deployments; and a disinclination to cooperate with
Japan, based on the disputes described in previous sections.

U.S.-South Korea Relations
Congressional Concern about U.S. Troop Deployments
In 2011, some Members of Congress raised strong concerns about existing plans to relocate U.S.
bases in South Korea and “normalize” the tours of U.S. troops there, including longer stays with
family members accompanying them. In May 2011, Senators Carl Levin, John McCain, and
James Webb issued a statement that urged a reconsideration of the existing plans for U.S. military
presence in the Asia Pacific, including the current agreements in South Korea. A Government
Accountability Office (GAO) report requested by Members of the Senate Appropriations
Committee released in May 2011 concluded that the Department of Defense had not
demonstrated a “business case” to justify the tour normalization initiative, nor considered
alternatives.29 In June 2011, the Senate Armed Services Committee passed amendments to the
2012 National Defense Authorization Act that prevents the obligation of any funds for tour
normalization until further reviews of the plan are considered and a complete plan is provided to
Congress. The National Defense Authorization Act for Fiscal Year 2013 (H.R. 4310/P.L. 112-239)
includes a provision (Section 2107) that continues to prohibit funds for tour normalization.
Proponents of the existing plans say that such changes could restrict U.S. military capabilities and
readiness as well as jeopardize hard-fought agreements designed to make the U.S. military
presence more politically sustainable in South Korea.30 For the time being, at least, the
Department of Defense (DOD) has “stopped pursuing Tour Normalization as an initiative for
Korea.”31
U.S. Alliance and ROK Defense Reform Plans
Current security developments are taking place in the context of several concurrent defense plans.
The June 2009 Obama-Lee summit produced the “Joint Vision for the Alliance,” which
promised to enhance and globalize future defense cooperation. After the decision to delay the
transfer of wartime operational control (Opcon) from U.S. to ROK forces, the operational
“Strategic Alliance 2015” roadmap (announced in September 2010) outlined the new transition,
including a path forward for improvements in ROK capabilities and changes to U.S. troop
relocation and tour normalization. The U.S. military is also undergoing a broad transformation of
its forces in the region; the 8th Army is moving toward becoming a war fighting headquarters that
can deploy to other areas of the world while still serving as a deterrent to any possible aggression
from North Korea.32
Meanwhile, South Korea’s Defense Reform 2020 bill passed by the National Assembly in 2006
laid out a 15-year, 621 trillion won (about $550 million) investment that aimed to reduce the
number of ROK troops while developing a high-tech force and strengthening the Joint Chiefs of
Staff system. In addition, a plan known as “Defense Reformation Plan 307” was intended to
enhance collaboration among the ROK military branches. Responding to the North Korean
provocations of 2010, the new “proactive deterrence” approach calls for a more flexible posture
to respond to future attacks, as opposed to the “total war” scenario that has driven much of

Seoul’s defense planning in the past. The defense reforms announced by the Park Administration
in March 2014 aim to restructure the ground operations command, which will allow the South
Korean military to conduct nimbler operations in response to low-intensity provocations.33 The
reforms also plan to raise the pay of Korean military personnel while reducing the size of the
force from the current 655,000 servicemembers to 522,000 by 2022. Despite these changes, the
conservative Lee and Park Administrations have slowed significantly the defense budget
increases planned under the earlier, progressive Roh Moo-hyun Administration (2003-2008).
The Relocation of U.S. Forces Korea (USFK)
In 2004, Secretary of Defense Donald Rumsfeld authorized a realignment program to reduce and
relocate U.S. forces in South Korea. Under the Rumsfeld program, the Pentagon withdrew a
3,600-person combat brigade from the Second Division and sent it to Iraq. The Rumsfeld plan
called for the U.S. troop level in South Korea to fall from 37,000 to 25,000 by September 2008.
However, in 2008, Secretary of Defense Bob Gates halted the withdrawals at the level of 28,500.
The realignment plan reflects the shift toward a supporting role for USFK and a desire to resolve
the issues arising from the location of the large U.S. Yongsan base in downtown Seoul.
The USFK base relocation plan has two elements. The first envisages the transfer of a large
percentage of the 9,000 U.S. military personnel at the Yongsan base to U.S. Army Garrison
(USAG) Humphreys, which is located near the city of Pyeongtaek some 40 miles south of Seoul.
The second element involves the relocation of about 10,000 troops of the Second Infantry
Division from the demilitarized zone to areas south of the Han River (which runs through Seoul).
The end result would be that USFK’s sites will decline to 48, from the 104 it maintained in 2002.
The bulk of U.S. forces will be clustered in the two primary “hubs” of Osan Air Base/USAG
Humphreys and USAG Daegu that contain five “enduring sites” (Osan Air Base, USAG
Humphreys, USAG Daegu, Chinhae Naval Base, and Kunsan Air Base). In late 2013, USFK
Commander General Curtis Scaparrotti indicated that some “residual” staff may continue to fulfill
the so-called “tripwire” function of U.S. forces stationed near the DMZ.34 South Korean defense
officials maintain that no U.S. military units will be stationed north of Seoul.
The relocations to Pyeongtaek originally were scheduled for completion in 2008, but have been
postponed several times because of the slow construction of new facilities at Pyeongtaek and
South Korean protests of financial difficulties in paying the ROK share of the relocation costs.
The commander of the U.S. Army Corps of Engineers assessed that the entire troop realignment
was 42% complete as of May 2014 and is on track to finish in 2017.35 The original cost estimate
was over $10 billion; South Korea was to contribute $4 billion of this. Estimates in 2010 placed
the costs at over $13 billion. In congressional testimony in September 2010, U.S. officials
demurred from providing a final figure on the cost of the move, but confirmed that the South
Koreans were paying more than the original $4 billion.36 The first battalion-sized element
relocated from a base in Uijeongbu, north of Seoul, to USAG Humphreys in late December

become the command center for U.S. forces after the planned transfer of wartime operational
control to South Korea.

Tour Normalization
Another complicating factor in the development of the Yongsan Relocation Plan is the
announcement by the Pentagon in 2008 that U.S. military families, for the first time, would be
allowed to join U.S. military personnel in South Korea. Most U.S. troops in South Korea serve
one-year unaccompanied assignments. The goal was to phase out one-year unaccompanied tours
in South Korea, replacing them with 36-month accompanied or 24-month unaccompanied tours.
Supporters of the plan argue that accompanied tours create a more stable force because of longer,
more comfortable tours. Eventually, the “normalization” of tours is estimated to increase the size
of the U.S. military community at Osan/Humphries near Pyeongtaek to over 50,000. However, in
January 2013, USFK released a statement saying, “while improvements to readiness remain the
command’s first priority, tour normalization is not affordable at this time.”38 An April 2013 Senate
Armed Services Committee (SASC) report criticized the policy change as expensive and
questioned the legality of how DOD calculated the housing allowance.39

U.S.-South Korea Relations
Cost Sharing
Since 1991, South Korea has provided financial support through a series of Special Measures
Agreements (SMAs) to offset the cost of stationing U.S. forces in Korea. In January 2014, Seoul
and Washington agreed to terms for the next five-year SMA, covering 2014-2018. Under the new
agreement, Seoul will raise its contribution by 6% to 920 billion Korean won ($867 million) in
2014 and then increase its annual payments at the rate of inflation. The new SMA also makes
U.S. use of South Korean funds more transparent than in the past, in response to South Korean
criticism. The ROK Ministry of Defense must approve every contract for which SMA funds are
obligated, and USFK will submit an annual report on the SMA funds to the National Assembly.
Even with these changes, Korean opposition lawmakers complained that the agreement is
“humiliating” and that USFK might use SMA funds to finance portions of the relocation plan (see
above) in violation of the 2004 agreement.
According to the aforementioned SASC report, U.S. military non-personnel costs in South Korea
totaled about $1.1 billion in 2012, and Korean SMA payments totaled 836 billion won ($765
million). In combination with that sum, other compensation outside the SMA (such as the South
Korea contribution to base relocation) provides for about 40%-45% of the total non-personnel
stationing costs for the U.S. troop presence.40 South Korean SMA payments have not kept pace
with rising U.S. costs. The 2013 SASC report says that between 2008 and 2012 South Korea’s
contributions grew by about $42 million (in line with the pace of inflation), while U.S. nonpersonnel costs increased by more than $500 million.
Opcon Transfer
The United States has agreed to turn over the wartime command of Korean troops to South
Korea, but the two sides will likely postpone this transfer for several years. Under the current
command arrangement, which is a legacy of U.S. involvement in the 1950-1953 Korean War,
South Korea’s soldiers would be under the command of U.S. forces if there were a war on the
peninsula. The plan to transfer wartime operational control was undertaken to recognize South
Korea’s advances in economic and military strength since the Korean War and is seen by many as
important for South Korean sovereignty. In 2007, Secretary Rumsfeld accepted a proposal by
President Roh Moo-hyun to set up separate South Korean and U.S. military commands by April
2012. A U.S.-ROK operational control agreement will dismantle the U.S.-ROK Combined Forces
Command (CFC), which has been headed by the U.S. commander in Korea. Separate U.S. and
ROK military commands will be established. In accord with the plan, a new U.S. Korea
Command (KORCOM) will be established. Under the Opcon agreement, a bilateral Military
Cooperation Center will be responsible for planning military operations, joint military exercises,
logistics support, and intelligence exchanges, and assisting in the operation of the
communication, command, control, and computer systems.
In 2010, the Opcon transfer was delayed after a series of provocations from North Korea and
amid concerns about whether South Korean forces were adequately prepared to assume
responsibility. As the new deadline of 2015 grew closer, concerns again emerged about the
timing: in 2013, media outlets reported that officials in Seoul had asked Washington to delay the
transfer. Reportedly, South Korean officials worry that their military is not fully prepared to cope
40

U.S.-South Korea Relations
with North Korean threats and that Pyongyang might interpret the Opcon transfer as a weakening
of the alliance’s deterrence.41 Some military experts expressed concern that turning over control
would lead to the United States reducing its overall commitment to South Korean security.42 In
April 2014, the United States and South Korea announced in a joint statement that the allies
would re-examine the timeline for Opcon transfer and determine the appropriate timing and
conditions. USFK Commander General Scaparrotti testified to Congress that the transfer will be a
“conditions-based process” and noted that the main areas of attention for the alliance will be
informational awareness, command communications systems, ballistic missile defense, and
munitions.43 Observers now believe that the Opcon transfer may not occur until 2020 or later.
The “Strategic Flexibility” of USFK
In 2007 and 2008, U.S. commanders in South Korea stated that the future U.S. role in the defense
of South Korea would be mainly an air force and naval role. The ROK armed forces today total
655,000 troops, with about 520,000 of them in the Army and around 65,000 each in the Air Force
and Navy. Since 2004, the U.S. Air Force has increased its strength in South Korea through the
regular rotation into South Korea of advanced strike aircraft. These rotations are not a permanent
presence, but the aircraft often remain in South Korea for weeks and sometimes months for
training.
Since the early 2000s, U.S. military officials have expressed a desire to deploy some U.S. forces
in South Korea to areas of international conflicts under a doctrine of “strategic flexibility.” The
South Korean government of Roh Moo-hyun resisted this idea, largely for fear it might entangle
South Korea in a possible conflict between the United States and China. In the mid-2000s, the
two governments reached an agreement in which South Korea recognized the United States’
intention to be able to deploy its forces off the Peninsula, while the United States in turn
recognized that the troops’ return to South Korea would be subject to discussion. Among other
elements, the compromise seems to imply that in an off-Peninsula contingency, U.S. forces might
deploy but not operate from South Korea.
Revision of South Korean Ballistic Missile Guidelines
In October 2012, South Korea announced that the United States had agreed to allow South Korea
to increase the maximum range of its ballistic missiles from 300 km (186 miles) to 800 km (500
miles) and to increase the payload limit from 500 kg (1,100 lbs.) to 1,000 kg (2,200 lbs.) if the
range is reduced proportionately.44 The revised missile guidelines had reportedly been under
negotiation for two years, following two conventional military attacks in 2010 by North Korea
against South Korean military and civilian targets. The South Korean and U.S. governments
characterized the revision as an effort to improve deterrence in response to the increased military
threat of North Korea, particularly its ballistic missiles. In March 2014, South Korea tested a new

ballistic missile with a 310-mile range, days after North Korea raised tensions with multiple
missile launches of its own. The revised guidelines do not violate the Missile Technology Control
Regime (MTCR), but critics argue that the United States has damaged its credibility to restrain
other countries’ missile development, including North Korea’s. Other analysts have raised
concerns about the impact of the agreement on the regional security environment in Northeast
Asia.45 Some analysts view North Korea’s December 2012 rocket launch (using ballistic missile
technology) partly as a response to the revised guidelines.46 Alliance politics may have
encouraged Washington to acquiesce to Seoul’s demands.47
South Korean Defense Industry and Purchases of U.S. Weapon Systems
South Korea is a major purchaser of U.S. weapon systems, taking delivery of $540 million worth
of U.S. arms in calendar year 2011. The country is regularly among the top customers for Foreign
Military Sales (FMS) and arranged large deals for 36 new AH-64E “Apache” attack helicopters
and 14 refurbished CH-47D “Chinook” cargo helicopters in late 2013. Although South Korea
generally buys the majority of its weapons from the United States, European and Israeli defense
companies also compete for contracts; Korea is an attractive market because of its rising defense
expenditures. According to Foreign Policy, however, U.S. officials are concerned that South
Korea is exploiting U.S. defense technology in its indigenously produced equipment, some of
which is exported to other countries.48
South Korea will reportedly purchase the Lockheed Martin F-35 Joint Strike Fighter to be its next
main fighter aircraft, after the Ministry of Defense in September 2013 threw out the yearlong
acquisition process that selected the Boeing F-15SE fighter.49 The cost of the F-35 had been too
high for the original bid, according to reports, but Korean defense officials determined that only
the F-35 met their requirements for advanced stealth capability. South Korea will purchase 40 F35 fighters at a total cost of $7.83 billion, with the first delivery of aircraft scheduled for 2018.50
Missile defense is an area of growing investment for the South Korean military. The ROK Navy
has three destroyers with Aegis tracking software but no missile interceptors, and the ROK Army
fields relatively unsophisticated PAC-2 interceptors, which are not suited for a ballistic missile
defense role. The budget requested by the Ministry of National Defense for FY2014 includes
significant funding to accelerate South Korea’s missile defense system; although most
components will come from the United States, South Korea has decided to develop its own
Korean Air and Missile Defense (KAMD) system instead of integrating with the U.S. regional
ballistic missile defense network. As plans for the KAMD unfold, the South Korean military will

reportedly seek to purchase PAC-3 interceptors, SM-2 surface-to-air missiles, and the more
advanced SM-6 air defenses.51
South Korea also intends to purchase U.S. unmanned aerial vehicles (UAVs). Reportedly, the
ROK military will buy four RQ-4 “Global Hawk” UAVs at a price of $845 million in total.52
Given concerns that the sale could violate the Missile Technology Control Regime (MTCR) and
non-proliferation norms, observers have called on the Obama Administration to ensure that the
Global Hawks are used strictly for reconnaissance and are not armed.53 Currently, the South
Korean military only operates reconnaissance UAVs, but the Ministry of National Defense is
budgeting $447 million to indigenously develop a combat UAV by 2021.54 The revised ballistic
missile guidelines also increased the maximum allowable payload for South Korean UAVs to
from 500 kg to 2,500 kg (5,500 lbs.), but the range is not limited by any international agreements.
Korea’s Defense Reform 2020 legislation emphasizes the development of indigenous capabilities
by increasing the percentage of funds allocated to defense research and development (R&D).55
South Korea aims to improve the competitiveness of its defense industry, but problems with the
reliability of certain systems pose a challenge; South Korean firms compete internationally in the
armored vehicle, shipbuilding, and aerospace industries.56 Of particular note is the T-50 Golden
Eagle, a trainer and light fighter aircraft developed in conjunction with Lockheed Martin.
The 110th Congress passed legislation that upgraded South Korea’s status as an arms purchaser
from a Major Non-NATO Ally to the NATO Plus Three category (P.L. 110-429), which has
become NATO Plus Five. This upgrade establishes a higher dollar threshold for the requirement
that the U.S. executive branch notify Congress of pending arms sales to South Korea, from $14
million to $25 million. Congress has 15 days to consider the sale and take legislative steps to
block the sale compared to 30 days for Major Non-NATO Allies.
South Korea’s Regional Relations
Looking at their surrounding neighborhood, South Koreans sometimes refer to their country as a
“shrimp among whales.” South Korea’s relations with China and Japan, especially the latter, are
fraught with ambivalence, combining interdependence and rivalry. Until 2013, trilateral
cooperation among the three capitals generally had been increasing, particularly in the aftermath
of the 2008 global financial crisis. Between 2009 and 2012, leaders of the three countries met
annually in standalone summits, established a trilateral secretariat in Seoul, signed an investment
agreement, and laid the groundwork for trilateral FTA negotiations to begin.57 In 2013, however,
tensions between South Korea and Japan, and between China and Japan, froze much of this

burgeoning trilateral cooperation. One exception was the trilateral FTA negotiations, which were
launched in March.
Park Geun-hye often speaks of a Northeast Asian “paradox,” in which there is a “disconnect
between growing economic interdependence on the one hand and backward political-security
cooperation on the other.” To resolve this situation, Park has proposed a “Northeast Asian Peace
and Cooperation Initiative” that would involve, among other items, Japan adopting a “correct
understanding of history,” and the United States and China forging a “forward-looking
relationship.”58 While the South Korean government has been vague about the proposal, a key
part of Park’s vision appears to be to start by holding multilateral meetings with regional
countries and the United States to discuss non-traditional security issues such as the environment,
disaster relief, and nuclear safety.
South Korea-Japan Relations
U.S. policy makers have long voiced encouragement for enhanced South Korea-Japan relations. A
cooperative relationship between the two countries, both U.S. treaty allies, and among the three is
in U.S. interests because it arguably enhances regional stability, helps coordination over North
Korea policy, and boosts each country’s ability to deal with the strategic challenges posed by
China’s rise. However, despite increased cooperation, closeness, and interdependence between
the South Korean and Japanese governments, people, and businesses over the past decade,
mistrust on historical and territorial issues continues to linger. South Korea and Japan have
competing claims to the small Dokdo/Takeshima islands in the Sea of Japan (called the East Sea
by Koreans), and most South Koreans complain that Japan has not adequately acknowledged its
history of aggression against Korea.59 For more than three generations beginning in the late 19th
century, Japan intervened directly in Korean affairs, culminating in the annexation of the Korean
peninsula in 1910. Over the next 35 years, Imperial Japan all but attempted to wipe out Korean
culture.60 Among the victims were tens of thousands of South Korean “comfort women” who
during the 1930s and 1940s were recruited, many if not most by coercive measures, into
providing sexual services for Japanese soldiers. Whenever South Koreans perceive that Japanese
officials are downplaying or denying this history, it becomes difficult for South Korean leaders to
back initiatives to institutionalize improvements in bilateral ties.
From 2008 to 2011, former President Lee sought to separate historical issues from the larger
relationship. In this, he was aided by Japanese leaders from the Democratic Party of Japan (DPJ)
who often tended to be more willing to acknowledge Imperial Japan’s actions against Korea and
who placed a priority on improving relations with Seoul. Cemented for the first time in years by a
common strategic outlook on North Korea, trilateral South Korea-U.S.-Japan coordination over
North Korea policy was particularly close. People-to-people ties blossomed, with tens of
thousands of Japanese and Koreans traveling to the other country every day. The South Korean

Since the early 1950s, South Korea has administered Dokdo/Takeshima, which the U.S. government officially calls
the “Liancourt Rocks.”

Many Koreans believe that the United States was complicit in this history, by reportedly informally agreeing in a
1905 meeting between U.S. Secretary of War William Taft and Japanese Prime Minister Taro Katsura that the United
States would recognize Japan’s sphere of influence over Korea in return for Japan doing the same for the United States
in the Philippines.

U.S.-South Korea Relations
and Japanese militaries also stepped up their cooperation, including holding trilateral exercises
with the United States.
However, South Koreans’ interest in forming significant new institutional arrangements with
Japan is dampened by three domestic factors in South Korea. First, continued suspicions of Japan
among the South Korean population place political limitations on how far and how fast Korean
leaders can improve relations. Second, continued disagreements over Dokdo/Takeshima’s
sovereignty continue to weigh down the relationship. Third, unlike Japan, South Korea generally
does not view China as an existential challenge and territorial threat. South Korea also needs
Chinese cooperation on North Korea. Accordingly, South Korean leaders tend to be much more
wary of taking steps that will alarm China. A factor that could change this calculation is if China
is seen as enabling North Korean aggression. Indeed, North Korean acts of provocation are often
followed by breakthroughs in ROK-Japan relations, as well as in ROK-U.S.-Japan cooperation.
All three of these factors contributed to a dramatic downturn in South Korea-Japan relations in
2012. In May and again in June, the two sides were on the verge of signing a completed
intelligence-sharing agreement long sought by the United States as a way to ease trilateral
cooperation and dialogue. However, a firestorm of criticism against the pact in South Korea led
the Lee government to cancel the signing minutes before it was to take place. Negotiations over a
related deal on exchanging military supplies also broke down. Later that summer, President Lee
made the first-ever visit by a South Korean president to Dokdo/Takeshima. Lee said his visit was
in large measure a response to what he claimed was Japan’s failure to adequately acknowledge
and address the suffering of the World War II comfort women.

in U.S. Government publications. The Republic of Korea refers to this body of water as the “East Sea.” It refers
to the “Yellow Sea” as the “West Sea.” For more, see the “Sea of Japan/East Sea Naming Controvers” section.
From this low base, relations worsened after the elections of Park Geun-hye and Abe Shinzo.
Neither leader appears willing to be seen as compromising with the other. Moreover, the
approaches of both leaders to historical issues appear to contradict one another and are locked in a
vicious circle: Park seeks to bring Japan to a more full-throated acknowledgement and apology
for its pre-WWII actions, and has linked other aspects of South Korea-Japan relations to the
history issue. Meanwhile, Abe aims to restore Japanese pride in its history by erasing many signs
of what many Japanese nationalists have regarded as self-flagellation, such as the portrayal of the
early 20th century in history textbooks. Given the array of domestic forces opposed to raising
South Korea-Japan relations to a new level, it is unclear whether the two governments will have
the interest or capacity to do more than maintain ad hoc cooperation, such as in response to
aggressive North Korean actions.
Sea of Japan/East Sea Naming Controversy
For centuries, South Korea and Japan have used different names to refer to the sea that lies
between the main islands of the Japanese archipelago and mainland Asia. Japan refers to these
waters as the “Sea of Japan,” while South Korea and North Korea refer to them as the “East
Sea.”61 “Sea of Japan” is the name used in a majority of atlases, by most international institutions,
and by most governments, including the United States government.62 The South Korean
government urges the concurrent use of both names, perhaps for an interim period, until only
“East Sea” is universally recognized.63 Japan opposes attempts to either replace the “Sea of
Japan” with “East Sea” or to use both names concurrently. For many Koreans, the predominant
use of “Sea of Japan” is a legacy of the period when Korea was under Japanese rule, because a
number of key decisions about the world’s geographic names were made during the first half of
the 20th century.
In recent years, the South Korean government, South Korean citizens, and some Korean
Americans appear to have been broadening their appeal to atlas publishers, U.S. federal
government institutions, and the legislatures of some U.S. states such as Virginia and New York.
The South Korean government states that there is a “steady increase” in maps using both names.64
The Japanese government states that the name Sea of Japan is “overwhelmingly” used.65
61
Other countries also use the name “East Sea” to refer to different bodies of water. For instance, the body of water
commonly referred to as the “South China Sea” is referred to as the “East Sea” by Vietnam.
62
For instance, in 2012, the International Hydrographic Organization (IHO), an intergovernmental organization that
creates widely-used reference sources on the names and borders of waters around the world, decided not to change its
naming protocol of using only “Sea of Japan.”
63
The South Korean effort began in 1992, when shortly after they joined the United Nations, South Korea and North
Korea began urging that “East Sea” be included on world maps. JoongAng Ilbo, “Gov’t Goes Easy on East Sea

In the United States, geographic place name policies for federal government agencies are set forth
by the Board on Geographic Names (BGN), pursuant to P.L. 80-242. The BGN’s policy is that “a
single conventional name, if one exists, will be chosen as the standard name” for seas and oceans.
The BGN decides on what constitutes a “conventional name” by consulting various print and
online geographic references to determine which name is “under widespread and current usage.”66
South Korea-China Relations
Park Geun-hye has placed a priority on improving South Korea’s relations with China, which are
generally thought to have been cool during Lee Myung-bak’s tenure. In June 2013, Park traveled
to China for what was generally regarded as a successful visit that included meetings with
Chinese President Xi Jinping. Since then, the two sides have expanded a number of high-level
arrangements designed to boost strategic communication and dialogue. In June 2014, President Xi
made a reciprocal visit to Seoul. Notably, his first visit to the Korean Peninsula as President was
to South Korea, not to China’s ally, North Korea.
One exception to the warming of ROK-China relations was Beijing’s creation of its East China
Sea air defense identification zone (ADIZ) in November 2013. South Korea voiced strong
displeasure with the Chinese ADIZ, which overlapped slightly with the existing South Korean
ADIZ, and reportedly asked China in a meeting of defense officials to redraw the boundary. This
request was denied, and South Korea decided to expand its own ADIZ, creating greater
overlapping areas with the Chinese and Japanese ADIZs. Thus far, the ADIZ issue does not
appear to have seriously damaged relations between Seoul and Beijing.
China’s rise influences virtually all aspects of South Korean foreign and economic policy. North
Korea’s growing economic and diplomatic dependence on China since the early 2000s has meant
that South Korea must increasingly factor Beijing’s actions and intentions into its North Korea
policy. China’s influence over North Korea has tended to manifest itself in two ways in Seoul. On
the one hand, most South Korean officials worry that North Korea, particularly its northern
provinces, is drifting into China’s orbit. For those on the political left in South Korea, this was an
argument against Lee’s harder line stance toward inter-Korean relations, which they say has
eroded much of South Korea’s influence over North Korea.
On the other hand, China’s continued support for North Korea, particularly its perceived backing
of Pyongyang after the Yeonpyeong Island shelling in 2010, has angered many South Koreans,
particularly conservatives. China’s treatment of North Korean refugees, many of whom are
forcibly repatriated to North Korea, has also become a bilateral irritant. Many South Korean
conservatives also express concern that their Chinese counterparts have been unwilling to discuss
plans for dealing with various contingencies involving instability in North Korea, though there
were signs in 2013 and early 2014 that Beijing was becoming more willing to engage in these
discussions. Park Geun-hye has called for establishing a trilateral strategic dialogue among
Korea, the United States, and China.67
Since China’s 2001 entry into the World Trade Organization, China has emerged as South Korea’s
most important economic partner. Over 20% of South Korea’s total trade is with China, twice the

level for South Korea-U.S. and South Korea-Japan trade.68 For years, China has been the number
one location for South Korean firms’ foreign direct investment, and South Korea is negotiating a
bilateral FTA with China. Yet, even as China is an important source of South Korean economic
growth, it also looms large as an economic competitor. Indeed, fears of increased competition
with Chinese enterprises have been an important motivator for South Korea’s push to negotiate a
series of FTAs with other major trading partners around the globe.
Some U.S. officials, including some Members of Congress, have raised concerns that the security
of the U.S. military’s telecommunications infrastructure could be compromised by the plans of
LG Uplus, South Korea’s third-largest mobile carrier, to buy equipment from Chinese telecom
giant Huawei for an advanced wireless network.69
South Korea-Iran Relations70
In December 2012, the Obama Administration granted South Korea a 180-day extension of its
exemption from U.S. sanctions on Iran as a result of South Korea’s curtailing of oil imports from
Iran. P.L. 112-81, the National Defense Authorization Act for Fiscal Year 2012, places strict
limitations on the U.S. operations of foreign banks that conduct transactions with Iran’s Central
Bank. Foreign banks can be granted an exemption from sanctions if the President certifies that the
parent country of the bank has significantly reduced its purchases of oil from Iran. South Korea is
one of the largest importers of Iranian oil. Following extensive negotiations between the Obama
and Lee governments in early 2012, South Korean imports of Iranian oil fell sharply. As of late
2013 they averaged around 40% the level that South Korea was importing in 2011. In response to
these cutbacks, the Obama Administration has issued periodic waivers that exempt Seoul from
U.S. sanctions that otherwise would apply because of South Korea’s continued imports of oil
from Iran. Additionally, under a November 2013 interim agreement between Iran, the United
States, and five other countries, from January 2014 to June 2014, the United States will pause its
efforts to further reduce Iran’s crude oil sales, including sales to South Korea.71
Over the past decade, growing concerns over Iran’s nuclear program have led to increased U.S.
scrutiny of South Korea’s long-standing trade with and investments in Iran. South Korea is one of
the most important customers for Iranian oil.72 A number of South Korean conglomerates (called
chaebol) have received significant contracts to build or service large infrastructure projects in
Iran, including in Iran’s energy sector. Additionally, Iran has been a significant regional hub for
thousands of smaller South Korean manufacturers, which ship intermediate goods to Iran that are
then assembled into larger units and/or re-exported to other Middle Eastern countries.
68
Much of South Korea’s exports to China are intermediate goods that ultimately are used in products exported to the
United States and Europe.
69
In the fall of 2013, Senators Dianne Feinstein and Robert Menendez reportedly wrote to the Obama Administration
with concerns about the proposed deal. In 2012, the House Permanent Select Committee on Intelligence released a
study titled “Investigative Report on the U.S. National Security Issues Posed by Chinese Telecommunications
Companies Huawei and ZTE,” which was critical of the Chinese firm.

U.S.-South Korea Relations
Economic Relations
South Korea and the United States are major economic partners. In 2013, two-way trade between
the two countries totaled around $100 billion (see Table 1), making South Korea the United
States’ sixth-largest trading partner. For some western states and U.S. sectors, the South Korean
market is even more important. South Korea is far more dependent economically on the United
States than the United States is on South Korea. In 2013, the United States was South Korea’s
second-largest trading partner, second-largest export market, and the third-largest source of
imports. It was among South Korea’s largest suppliers of foreign direct investment (FDI).
As South Korea has emerged as a major industrialized economy, and as both countries have
become more integrated with the world economy, economic interdependence has become more
complex and attenuated. In particular, the United States’ economic importance to South Korea has
declined relative to other major powers. In 2003, China for the first time displaced the United
States from its perennial place as South Korea’s number one trading partner. Japan and the 28member European Union each also rival and have at times surpassed the United States as South
Korea’s second-largest trading partner.
South Korea’s export-driven economy and subsequent competition with domestic U.S. producers
in certain products has also led to some trade frictions with the United States. For example,
imports of certain South Korean products—mostly steel or stainless steel items as well as
polyester, chemicals, and washing machines—have been the subject of U.S. antidumping and
countervailing duty investigations. As of May 29, 2014, antidumping duties were being collected
on 12 South Korean imports and countervailing duties were being assessed on 3 South Korean
products, and there were 3 ongoing new investigations involving South Korean goods.73
In October 2011, the House and Senate passed H.R. 3080, the United States-Korea Free Trade
Agreement Implementation Act, which was subsequently signed by President Obama.74 In March
2012, the U.S.-South Korea FTA (KORUS FTA) entered into force. The George W. Bush and Roh
Moo-hyun Administrations initiated the KORUS FTA negotiations in 2006 and signed an
agreement in June 2007.75
Upon the date of implementation of the KORUS FTA, 82% of U.S. tariff lines and 80% of South
Korean tariff lines were tariff free in U.S.-South Korean trade, whereas prior to the KORUS FTA,
38% of U.S. tariff lines and 13% of South Korean tariff lines were duty free. By the 10th year of
the agreement, the figures will rise to an estimated 99% and 98%, respectively, with tariff
elimination occurring in stages and the most sensitive products having the longest phase-out
periods. Non-tariff barriers in goods trade and barriers in services trade and foreign investment
are to be reduced or eliminated under the KORUS FTA.
At the time of this writing, the KORUS FTA had been in force for just over two years; therefore it
is too early to ascertain its overall impact on U.S.-South Korean bilateral trade. Nevertheless,
Table 1 below presents U.S.-South Korea merchandise trade data for selected years; total bilateral
trade grew by around 2.9% in 2013 compared to 2012. U.S. exports to South Korea declined by

South Korea’s Economic Performance
South Korea was hit hard by the global financial crisis that began in late 2008, because of its
heavy reliance on international trade and its banks’ heavy borrowing from abroad. Real GDP
growth declined to 0.2% in 2009. However, the South Korean economy roared back and grew by
6.2% in 2010. The government took strong countermeasures to blunt the crisis’s impact, engaging
in a series of fiscal stimulus actions worth about 6% of the country’s 2008 GDP, by some
measures the largest such package in the Organization for Economic Cooperation and
Development (OECD) group of industrialized countries. The Bank of Korea (BOK) also acted
aggressively, lowering interest rates from over 5% to a record low 2% and engaging in a range of
other operations, estimated by the OECD to be worth over 2.5% of GDP, designed to infuse
liquidity in the Korean economy. The BOK negotiated currency swap agreements with the United
States, Japan, and China.76 The South Korean won, after depreciating to around 1,500
won/dollar—a fall of nearly one-third from early 2008 to early 2009—has gradually strengthened
against the dollar, to the 1,000-1,100 won/dollar range. The won’s depreciation in 2008 and 2009
helped to stimulate South Korea’s economic recovery by making its exports cheaper relative to
many other currencies, particularly the Japanese yen.
76
The October 2008 swap agreement with the U.S. Federal Reserve gave Bank of Korea access to up to $30 billion in
US dollar funds in exchange for won.
Congressional Research Service
28
U.S.-South Korea Relations
Since 2010, South Korean real GDP growth has slowed, in part due to a slowdown in its foreign
trade and the won’s appreciation. South Korea’s economy is highly dependent upon capital
inflows and exports, the latter of which are equal to around half of the country’s annual GDP.
Thus, South Korea remains vulnerable to a slowdown in its major export markets: China, the
United States, the European Union, and Japan. GDP growth in 2011 was 3.6%, 2% in 2012, and
3.0% in 2013.
Although South Korea’s economic performance may look favorable to many around the world,
complaints in South Korea have risen in recent years that only rich individuals and large
conglomerates (called chaebol) have benefitted from the country’s growth since the 2008-2009
slowdown. The 2012 presidential election was largely fought over the issues of governance (in
the wake of a number of corruption scandals), social welfare, and rising income inequality.
Leading figures in both parties, as well as President Park and former President Lee, have
proposed ways to expand South Korea’s social safety net. As mentioned in the politics section
below, lower-than-expected growth for 2013 and 2014 has contributed to Park’s scaling back her
plans. South Korea has one of the lowest rates of social welfare spending in the industrialized
world. The rapid ageing of the South Korean population is expected to create additional financial
pressures on government expenditures in the future.
Nuclear Energy and Non-Proliferation Cooperation
Bilateral Nuclear Energy Cooperation77
The United States and South Korea have cooperated in the peaceful use of nuclear energy for
over 50 years.78 This cooperation includes commercial projects as well as R&D work on safety,
safeguards, advanced nuclear reactors, and fuel cycle technologies. As mentioned in the
introductory section of this report, the two countries have announced a two-year extension of
their bilateral civilian nuclear cooperation agreement, often referred to as a “123 agreement,”
which would have expired in March 2014.79 An extension of the agreement was approved by
Congress (S. 1901) in January and passed into law (P.L. 113-81). Renewing the agreement is
necessary because the existing agreement was concluded before the current requirements under
Section 123a of the Atomic Energy Act (as amended) (AEA) were enacted, and the existing
agreement does not meet all of the AEA’s requirements.
One of the reasons Seoul and Washington decided on a two-year extension is to give more time to
negotiators to work out a sticking point in the talks—how to treat fuel cycle issues. South Korea
reportedly requested that the new agreement include a provision that would give permission in
advance for U.S.-obligated spent nuclear fuel to be reprocessed to make new fuel using a type of
reprocessing called pyroprocessing.80 The United States and South Korea are jointly researching

pyroprocessing, but the technology is at the research and development stage.81 The Obama
Administration would prefer to approve such activities on a case-by-case basis (referred to as
“programmatic consent”), as is provided for under the current agreement. The South Korean
government is reportedly also seeking confirmation in the renewal agreement of its right to build
enrichment plants.
For several decades, the United States has pursued a policy of limiting the spread of enrichment
and reprocessing technology to new states as part of its nonproliferation policies.82 This is
because enrichment and reprocessing can create new fuel or material for nuclear weapons.
Advance permission to reprocess rarely has been included in U.S. nuclear cooperation
agreements, and to date has only been granted to countries that already had the technology (such
as to India, Japan, and Western Europe). However, the issue has become a sensitive one in the
U.S.-ROK relationship. Many South Korean officials and politicians see the United States’ rules
as limiting South Korea’s national sovereignty by requiring U.S. permission for civilian nuclear
activities. This creates a dilemma for U.S. policy as the Obama Administration has been a strong
advocate of limiting the spread of fuel cycle facilities to new states, and would prefer multilateral
solutions to spent fuel disposal.
Spent fuel disposal is a key policy issue for South Korean officials, and some see pyroprocessing
as a potential solution. While reactor-site spent fuel pools are filling up, the construction of new
spent fuel storage facilities is highly unpopular with the public. Some officials argue that in order
to secure public approval for an interim storage site, the government needs to provide a long-term
plan for the spent fuel. However, some experts point out that by-products of spent fuel
reprocessing would still require long-term storage and disposal options. Other proponents of
pyroprocessing see it as a way to advance energy independence for South Korea.
For decades, the United States and South Korea have worked on joint research and development
projects to address spent fuel. In the 1990s, the two countries worked intensely on research and
development on a different fuel recycling technology (the “DUPIC” process), but this technology
ultimately was not commercialized. In the past 10 years, joint research has centered on
pyroprocessing. The Korean Atomic Energy Research Institute (KAERI) is conducting a
laboratory-scale research program on reprocessing spent fuel with an advanced pyroprocessing
technique. U.S.-South Korean bilateral research on pyroprocessing began in 2002 under the
Department of Energy’s International Nuclear Energy Research Initiative (I-NERI). R&D work
on pyroprocessing was temporarily halted by the United States in 2008, due to the proliferation
sensitivity of the technology. In an attempt to find common ground and continue bilateral
research, in October 2010 the United States and South Korea began a 10-year Joint Fuel Cycle
Study on the economics, technical feasibility, and nonproliferation implications of spent fuel
disposition, including pyroprocessing. In July 2013, a new agreement on R&D technology
(...continued)
Nonproliferation Act, consent rights apply to material originating in the U.S. or material that has been fabricated into
fuel or irradiated in a reactor with U.S. technology. The majority of South Korea’s spent fuel would need U.S. consent
before it could be reprocessed.
81
Reprocessing of spent nuclear fuel can be used to make new reactor fuel or to separate out plutonium in the spent
fuel for weapons use. Pyroprocessing, or electro-refining, is a non-aqueous method of recycling spent fuel into new fuel
for fast reactors. It only partially separates plutonium and uranium from spent fuel. There is debate over the
proliferation implications of this technology.

transfer for joint pyroprocessing work in the United States took effect as part of the Joint Fuel
Cycle Study.83
While the Korean nuclear research community argues for development of pyroprocessing
technology, the level of consensus over the pyroprocessing option among Korean government
agencies, electric utilities, and the public remains uncertain. Generally, there appears to be
support in South Korea for research and development of the technology. Some analysts are
concerned about the economic and technical viability of commercializing the technology. While
the R&D phase would be paid for by the government, the private sector would bear the costs of
commercialization. At a political level, pyroprocessing may have more popularity as a symbol of
South Korean technical advancement and the possibility of energy independence. Some argue that
South Korea should have the independent ability to provide fuel and take back waste from new
nuclear power countries in order to increase its competitive edge when seeking power plant
export contracts. The Park Administration is conducting a review of the country’s spent fuel
policies.
Some analysts critical of the development of pyroprocessing in South Korea point to the 1992
Joint Declaration, in which North and South Korea agreed they would not “possess nuclear
reprocessing and uranium enrichment facilities” and are concerned about the impact of South
Korea’s pyroprocessing on negotiations with the North. Others emphasize that granting
permission for pyroprocessing in South Korea would contradict U.S. nonproliferation policy to
halt the spread of sensitive technologies to new states. Some observers, particularly in South
Korea, point out that the United States has given India and Japan consent to reprocess, and argue
that they should be allowed to develop this technology under safeguards.
South Korea and the United States have several options on how to treat this issue in the
negotiations over a new nuclear cooperation agreement. One option would be to renew the
agreement without granting any prior consent, and apply for programmatic consent in the future
as required (i.e., the same provisions as the current agreement). Another would be for South
Korea to seek long-term advance consent for pyroprocessing. Alternatively, South Korea could
seek programmatic consent for research and development of the technology and could then ask
for further consent for commercialization if it decided to go that route at a future date.
Since the technology has not been commercialized anywhere in the world, the United States and
the International Atomic Energy Agency (IAEA) are working with the South Korean government
to develop appropriate IAEA safeguards should the technology be developed further. Whether
pyroprocessing technology can be sufficiently monitored to detect diversion to a weapons
program is a key aspect of the Joint Study.
South Korean Nonproliferation Policy
South Korea has been a consistent and vocal supporter of strengthening the global
nonproliferation regime, which is a set of treaties, voluntary export control arrangements, and
other policy coordination mechanisms that work to prevent the spread of nuclear, biological, and
chemical weapons and their delivery systems. South Korea destroyed all of its chemical weapons
stocks by 2008, under the Chemical Weapons Convention.84 South Korea is a member of the
83
Federal Register, Vol. 708, No. 105, May 31, 2013.
South Korea has not recognized this stockpile publicly, and chose to destroy the weapons under the CWC

Nuclear Suppliers’ Group (NSG), which controls sensitive nuclear technology trade, and adheres
to all international nonproliferation treaties and export control regimes. South Korea also
participates in the G-8 Global Partnership, and other U.S.-led initiatives—the Proliferation
Security Initiative, the International Framework for Nuclear Energy Cooperation (formerly
GNEP), and the Global Initiative to Combat Nuclear Terrorism. South Korea has contributed $1.5
million to the United States’ nuclear smuggling prevention effort, run by the Department of
Energy, as part of its G8 Global Partnership pledge.85 South Korea has also contributed to the
Organization for the Prohibition of Chemical Weapons (OPCW) Trust Fund to support the
destruction of Syrian chemical weapons.
An Additional Protocol (AP) to South Korea’s safeguards agreement with the International
Atomic Energy Agency (IAEA) entered into force as of February 2004. This gives the IAEA
increased monitoring authority over the peaceful use of nuclear technology. In the process of
preparing a more complete declaration of nuclear activities in the country, the Korean Atomic
Energy Research Institute (KAERI) disclosed previously undeclared experiments in its research
laboratories on uranium enrichment in 2000, and on plutonium extraction in 1982. The IAEA
Director General reported on these undeclared activities to the Board of Governors in September
2004, but the Board did not report them to the U.N. Security Council. In response, the Korean
government reconfirmed its cooperation with the IAEA and commitment to the peaceful use of
nuclear energy, and reorganized the oversight of activities at KAERI. The experiments reminded
the international community of South Korea’s plans for a plutonium-based nuclear weapons
program in the early 1970s under President Park Chung-hee, the father of the current President
Park. Deals to acquire reprocessing and other facilities were canceled under intense U.S. pressure,
and Park Chung-hee eventually abandoned weapons plans in exchange for U.S. security
assurances. The original motivations for obtaining fuel cycle facilities as well as the undeclared
experiments continue to cast a shadow over South Korea’s long-held pursuit of the full fuel cycle.
As a result, since 2004, South Korea has aimed to improve transparency of its nuclear programs
and participate fully in the global nonproliferation regime. In addition, the 1992 Joint Declaration
between North and South Korea says that the countries “shall not possess nuclear reprocessing
and uranium enrichment facilities.” Since North Korea has openly pursued both of these
technologies, an intense debate is underway over whether South Korea should still be bound by
those commitments. Some analysts believe that an agreement with North Korea on
denuclearization could be jeopardized if South Korea does not uphold the 1992 agreement.
Of recent significance, South Korea hosted the 2012 Nuclear Security Summit, a forum initiated
by President Obama shortly after his inauguration. This was the second such summit after the
2010 Washington, DC, event. The South Korean government agreed to host the summit because it
fit into the “Global Korea” concept of international leadership and summitry; it was a chance for
the South Korean nuclear industry to showcase its accomplishments; and the South Korean
government was able to emphasize South Korea’s role as a responsible actor in the nuclear field,
in stark contrast with North Korea. It was also an important symbol of trust between the U.S. and
South Korean Presidents.

U.S.-South Korea Relations
South Korean Politics
As of early 2014, South Korean politics continued to be dominated by Park Geun-hye (born in
1952) and her conservative Saenuri (“New Frontier”) Party (NFP), which controls the legislature.
Ms. Park was elected in December 2012, becoming not only South Korea’s first woman
president, but also the first presidential candidate to receive more than half of the vote (she
captured 51.6%) since South Korea ended nearly three decades of authoritarian rule in 1988. She
will serve until February 2018. By law, South Korean presidents serve a single five-year term.
Park is the daughter of the late Park Chung-hee, who ruled South Korea from the time he seized
power in a 1961 military coup until his assassination in 1979.
According to the Asan Institute’s daily polling service, Park’s public approval ratings were in the
60%-70% range for much of 2013, in part due to positive assessments of her handling of foreign
affairs, particularly inter-Korean relations. However, her poll numbers declined to the 50% range
by the end of the year, due to a number of factors, including a perception that her government had
done little to follow through on her campaign pledges to overcome South Korea’s economic
difficulties and strengthen its social safety net; the mounting evidence that the country’s
intelligence service had tried to influence the 2012 presidential election in her favor (though no
evidence has surfaced that Park knew of the matter); and her government’s handling of a railway
strike. In particular, Park’s favorability ratings have fallen among voters under 40, a development
that many expected; in the 2012 election under-40 voters chose Park’s opponent, the Democratic
United Party’s Moon Jae-In, by a wide margin. Likewise, those over 50 overwhelmingly voted
for Park and continue to be her strongest base of support.
A Short History of South Korean Presidential Changes
For most of the first four decades after the country was founded in 1948, South Korea was ruled by authoritarian
governments. The most important of these was led by President Park’s father, Park Chung-hee, a general who seized
power in a military coup in 1961 and ruled until he was murdered by his intelligence chief in 1979. The elder Park’s
legacy is a controversial one. On the one hand, he orchestrated the industrialization of South Korea that transformed
the country from one of the world’s poorest. On the other hand, he ruled with an iron hand and brutally dealt with
real and perceived opponents, be they opposition politicians, labor activists, or civil society leaders. For instance, in
the early 1970s South Korean government agents twice tried to kill then-opposition leader Kim Dae-jung, who in the
second attempt was saved only by U.S. intervention. The divisions that opened under Park continue to be felt today.
Conservative South Koreans tend to emphasize his economic achievements, while progressives focus on his human
rights abuses.
Ever since the mid-1980s, when widespread anti-government protests forced the country’s military rulers to enact
sweeping democratic reforms, democratic institutions and traditions have deepened in South Korea. In 1997, longtime dissident Kim Dae-jung was elected to the presidency, the first time an opposition party had prevailed in a South
Korean presidential election. In December 2002, Kim was succeeded by a member of his left-of-center party: Roh
Moo-hyun, a self-educated former human rights lawyer who emerged from relative obscurity to defeat establishment
candidates in both the primary and general elections. Roh campaigned on a platform of reform—reform of Korean
politics, economic policymaking, and U.S.-ROK relations. He was elected in part because of his embrace of massive
anti-American protests that ensued after a U.S. military vehicle killed two Korean schoolgirls in 2002. Like Kim Daejung, Roh pursued a “sunshine policy” of largely unconditional engagement with North Korea that clashed with the
harder policy line pursued by the Bush Administration until late 2006. Roh also alarmed U.S. policy makers by
speaking of a desire that South Korea should play a “balancing” role among China, the United States, and Japan in
Northeast Asia. Despite this, under Roh’s tenure, South Korea deployed over 3,000 non-combat troops to Iraq—the
third-largest contingent in the international coalition—and the two sides initiated and signed the KORUS FTA.
In the December 2007 election, former Seoul mayor Lee Myung-bak’s victory restored conservatives to the
presidency. Among other items, Lee was known for ushering in an unprecedented level of cooperation with the
United States over North Korea and for steering South Korea through the worst of the 2008-2009 global financial
Congressional Research Service
33
U.S.-South Korea Relations
crisis. Under the slogan “Global Korea,” he also pursued a policy of expanding South Korea’s participation in and
leadership of various global issues. During the final two years of his presidency, however, Lee’s public approval ratings
fell to the 25%-35% level, driven down by—among other factors—a series of scandals surrounding some of his
associates and family members, and by an increasing concern among more Koreans about widening income disparities
between the wealthy and the rest of society. Since the end of military rule in 1988, every former South Korean
president has been involved in scandal and in some cases criminal investigation within several months of leaving office.
A Powerful Executive Branch
Nominally, power in South Korea is shared by the president and the 300-member unicameral
National Assembly. Of these, 246 members represent single-member constituencies. The
remaining 54 are selected on the basis of proportional voting. National Assembly members are
elected to four-year terms. The president and the state bureaucracy continue to be the dominant
forces in South Korean policymaking, as formal and informal limitations prevent the National
Assembly from initiating major pieces of legislation.
Political Parties
Presently, there are two major political parties in South Korea: President Park’s conservative
Saenuri Party (which has been translated as “New Frontier Party” or NFP) and the opposition,
center-left New Politics Alliance for Democracy (NPAD).86 U.S. ties have historically been much
stronger with South Korea’s conservative parties.
The NFP has controlled the Blue House (the residence and office of South Korea’s president) and
the National Assembly since 2008. In the last National Assembly elections, held in April 2012,
the NFP—under the leadership of Park Geun-hye—shocked nearly all observers by winning a
slim majority. (See Figure 3.) For much of 2011, virtually all the political winds appeared to be
blowing in favor of the opposition, left-of-center parties, and many predicted they would achieve
a sweeping victory.87 Thus, even though the main opposition group now known as the NPAD
increased its seat tally by nearly 50%, to 127, the April vote was considered a humiliating defeat,
and the party’s leadership resigned soon thereafter. Although the NFP retained control of the
Assembly, its narrow majority could make it vulnerable if it loses any of its members.
86
The Saenuri Party formerly was known as the Grand National Party (GNP). The New Politics Alliance for
Democracy formerly was known as the Democratic Party.
87
Among the many signs of this trend: the progressive parties soundly defeated the ruling party in April 2011
legislative by-elections, a left-of-center activist (Park Won-Soon) won a vote for the Seoul mayoralty in October; the
approval ratings for President Lee and his party plummeted, due in part to a series of scandals; and in late 2011 and
early 2012 Korea’s major progressive parties either merged or decided to cooperate during the April National
Assembly elections.

Figure 3. Party Strength in South Korea’s National Assembly
As of March 2014
Notes: President Park Geun-hye is from the Saenuri (New Frontier) Party. The last nationwide legislative
elections were held in April 2012. The next elections are scheduled for April 2016. South Korea’s next
presidential election is scheduled for December 2017. By law, South Korean presidents are limited to one fiveyear term.
South Korea’s progressive political parties—now largely consolidated in the NPAD—controlled
the Blue House for 10 years, from 1998 to 2008. For a four-year period, from 2004 to 2008, a
progressive party was the largest political group in in the National Assembly and held a majority
for part of that period. After failing to retake the Blue House or National Assembly in 2012, the
progressive camp faces several more years without significant tools of power and influence
within the South Korean polity. In a move that may have an impact on the 2016 National
Assembly and 2017 presidential elections, a popular independent National Assemblyman, Ahn
Cheol-Su, joined forces with the then-Democratic Party to form the NPAD. In the past, the
NPAD’s predecessor parties have advocated positions that, if adopted, could pose challenges for
the Obama Administration’s Korea policy, including calling for the renegotiation of some
provisions of the KORUS FTA, and adopting a more conciliatory approach to North Korea.

The Overall State of U.S.-South Korea Relations
Since 2008, relations between the United States and South Korea (known officially as the
Republic of Korea, or ROK) arguably have been at their most robust since the formation of the
U.S.-ROK alliance in 1953. Cooperation on North Korea policy has been particularly close.
President Park Geun-hye and her predecessor, Lee Myung-bak, spoke before joint sessions of
Congress, in May 2013 and October 2011, respectively, and in 2011 Congress approved the South
Korea-U.S. Free Trade Agreement (KORUS FTA), the United States’ second-largest FTA, after
the North America Free Trade Agreement (NAFTA).
Notwithstanding the positive state of the relationship, in the coming months U.S.-South Korea
ties could be tested by developments in areas where the two countries occasionally disagree, most
prominently how best to handle South Korea-Japan relations and how to respond to Japan’s
efforts to expand the role of its military. 2015 marks the 50th anniversary of the normalization of
South Korea-Japan relations and the 70th anniversary of the end of World War II and the liberation
of the Korean Peninsula from its colonization by Imperial Japan, drawing attention to a legacy

that continues to bedevil bilateral relations between Seoul and Tokyo. President Park has
promoted a number of initiatives with North Korea that may go against the grain of U.S. policies
that increase pressure on Pyongyang, though she has been careful to keep these proposals modest
and to condition larger-scale initiatives on fundamental changes in the North Korean
government’s behavior. Additionally, many South Korean officials have a different strategic view
of China than their U.S. counterparts, often leading them to avoid taking steps or making
statements that antagonize Beijing.
MERS Outbreak Leads President Park to Postpone Summit
President Park was scheduled to travel to the United States for a summit with President Obama in
mid-June 2015, her first visit to the United States since May 2013. President Obama last visited
South Korea in April 2014. Less than a week before Park’s scheduled departure, however, she
announced that she was postponing the trip due to an outbreak of Middle East Respiratory
Syndrome (MERS).2 As of June 9 MERS was blamed for nine deaths and over 100 confirmed
cases in South Korea. Park’s government had come under criticism—including from members of
her political party—for an allegedly belated and inadequate initial response to the outbreak,
particularly in reportedly waiting more than two weeks after confirmation of the first MERS case
to disclose the names of hospitals and clinics where confirmed MERS infections had occurred.3
The criticism echoes similar reactions to the Park government’s response to a ferry disaster that
killed hundreds in April 2014. (See the section on “Park Geun-hye’s Political Standing,” below.)
On June 11, the Bank of Korea announced a quarter-point cut in South Korea’s base interest rate
in part because the MERS outbreak was causing a contraction in domestic consumption.4
Cooperation over North Korea Policy5
Dealing with North Korea is the dominant strategic element of the U.S.-South Korean
relationship. Since 2009, U.S.-ROK coordination over North Korea policy has been close, with
the two allies essentially forging a joint approach toward North Korea that contains elements of
pressure against and cooperation with Pyongyang. The U.S. and South Korea have placed
significant emphasis on the harder elements of their approach, including strengthening their
deterrence posture, calling attention to North Korea’s human rights violations, and refusing to
meet North Korean demands on issues such as scaling back U.S.-ROK military exercises. Many
critics have said that the Obama Administration’s approach is too passive, with some observers
charging that it applies insufficient pressure and others arguing that it provides insufficient
incentives for Pyongyang to change its behavior. 6 (See “North Korea in U.S.-ROK Relations”
below.)

in U.S. Government publications. The Republic of Korea refers to this body of water as the “East Sea.” It refers
to the “Yellow Sea” as the “West Sea.”
Inter-Korean Relations
In the first half of 2015, Park has continued to unveil details of her “trustpolitik” plan for
reducing tensions on the Korean Peninsula and establishing the foundation for re-unification.
Relations between the two Koreas have been especially poor since 2010, when two military
attacks by North Korea on South Korea resulted in Park’s predecessor Lee Myung-bak halting
nearly all regular inter-Korean interchange.7 According to Park’s vision, South Korea will
encourage North Korea to behave more cooperatively by strengthening South Korea’s defense
capabilities, applying pressure on Pyongyang, and providing incentives for the forging of trust
between the two Koreas. As part of the last item, Park has promoted a range of dialogues and
projects with North Korea, generally on a relatively small scale. Thus far, North Korea generally
has resisted Park’s outreach. The Kim Jong-un regime may feel particularly threatened by Park’s
calls for South Korea to prepare for and welcome reunification, which Park appears to assume
will occur largely on South Korea’s terms.
The Obama Administration publicly has backed Park’s trustpolitik strategy and appears
comfortable letting Seoul take the lead in trying to encourage more cooperative behavior from
Pyongyang. However, in the future, some of the cooperative elements of Park’s approach toward
North Korea could conflict with U.S. policy due to an inherent tension that exists in the two
countries’ views of Pyongyang. The United States’ predominant concern is North Korea’s
weapons of mass destruction (WMD) programs while South Korea’s top priorities are WMD
issues and promoting unification. H.R. 757, the North Korea Sanctions Enforcement Act, could
conflict with some of Park’s initiatives, such as her stated desire to “internationalize” the interKorean Kaesong Industrial Complex by attracting multinational investors.8 (For more on
cooperation over North Korea and inter-Korean relations, see “North Korea in U.S.-ROK
Relations,” below.)
South Korea-Japan Relations Stabilize, but Remain Tense
South Korea’s relations with Japan have been strained since 2012. This limits U.S. policy options
in Northeast Asia and periodically causes tensions between Washington and one or both of its two
allies in Northeast Asia. Seoul and Tokyo disagree over how Imperial Japan’s actions in the early

20th century should be handled in contemporary relations. The relationship is also challenged by
conflicting territorial claims and strategic and economic competition. However, relations between
Seoul and Tokyo have improved modestly since the fall of 2014. Bilateral working-level
discussions have increased, and regular high-level bilateral meetings resumed in 2014 and have
built up to the Cabinet level. In another sign of a bilateral thaw, in December 2014 the United
States, South Korea, and Japan signed a modest trilateral information sharing agreement.
Additionally, despite many private statements by South Korean officials expressing concern about
Japanese “remilitarization,” the Park government officially does not appear to have objected in
principle to Japan’s historic moves to expand the scope of its military’s activities.9
Earlier in her term, Park insisted that Japan adopt a “correct understanding of history” as a
prerequisite for nearly all cooperative initiatives.10 However, increasingly since the middle of
2014, her government has relaxed this position and adopted more of a two-track approach,
separating disputes over history from most other aspects of the relationship. South Korea’s
change in behavior appears to have been influenced by shifts in the correlation of powers in
Northeast Asia that made Park’s former stance less tenable: for example, high-level SinoJapanese ties, which had also been frozen for months, reopened in November 2014, and U.S.Japanese ties have deepened in the first half of 2015, as symbolized during Prime Minister Shinzo
Abe’s April 2015 visit to the United States.11 U.S. pressure to improve ties and Abe’s avoidance
of historically sensitive comments or moves also may have contributed to Seoul’s apparent
adjustment in tone.
Despite the thaw, bilateral relations remain generally tense. Park and Abe have yet to hold a
formal summit meeting. Following Abe’s April 2015 speech to a joint meeting of Congress,
Park’s government issued a statement saying that it was “deeply regrettable” that Abe had not
addressed historical grievances between Japan and South Korea.12 As of early June 2015, months
of bilateral negotiations do not appear to have produced a breakthrough in how to resolve
disagreements over whether and how Japan should again acknowledge and address the suffering
of the so-called “comfort women,” who were forced to provide sexual services to Japanese
soldiers during Imperial Japan’s conquest and colonization of several Asian countries in the 1930s
and 1940s, including Korea. The ongoing opportunity costs to the United States have led some
policy analysts to call for the United States to become more directly involved in trying to improve
relations between the two sides.13
Two developments to watch in summer 2015 are how the two countries mark the 50th anniversary
of their June 22, 1965, normalization treaty and the content of Prime Minister Abe’s expected
statement commemorating the 70th anniversary of the end of World War II. If past statements by
Abe’s predecessors are any guide, he is likely to issue his statement on or around August 15, the
date of Imperial Japan’s surrender. (For more, see “South Korea’s Regional Relations,” below.)

South Korea Expresses Interest in TPP
In South Korea has continued to express a desire to join the twelve-nation Trans-Pacific
Partnership (TPP) free trade agreement (FTA) talks.14 In fall 2013, after months of speculation,
the South Korean government signaled its “interest” in joining the negotiations. Since that time, it
has taken several of the domestic steps necessary for it to officially announce its intent to apply to
join the TPP negotiations, and it has engaged in multiple rounds of consultations with the twelve
TPP countries, including the United States. The size and strategic importance of the proposed TPP
would expand significantly if South Korea—East Asia’s third-largest economy—enters the
negotiations, although South Korea’s entry may not have a significant impact on U.S.-South
Korea trade flows given the existing bilateral U.S.-South Korea FTA (KORUS). One of Park’s
top policy agendas is reviving the country’s economy. To this end, her government has initiated a
trade strategy of entering into more FTAs, thereby making South Korea a “linchpin” of
accelerated economic integration in the region.15 South Korea is negotiating a number of FTAs,
including a bilateral agreement with China that the two countries signed in June 2015.
The Obama Administration has “welcomed” Korea’s interest in joining the talks, though United
States Trade Representative (USTR) officials also have indicated they will place priority on
concluding an agreement with the existing members before agreeing to the entry of any new
countries. The current TPP countries approach membership based on consensus and therefore
must reach unanimous agreement on South Korea’s entry before Seoul can join. The United
States may require some preliminary commitments from Seoul before it agrees to South Korea’s
participation in the negotiations—so called “confidence building measures” were required prior
to Canada, Japan, and Mexico’s joining the TPP negotiations. U.S. officials have linked support
for South Korea’s possible entry into the proposed TPP with South Korea’s willingness and
ability to resolve ongoing issues with the implementation of the KORUS FTA, although officials
have also noted that many—though not all—of the U.S. complaints regarding KORUS
implementation have been resolved.16 Ultimately, Congress must approve implementing
legislation if a completed TPP agreement—with or without South Korea—is to apply to the
United States. (For more on South Korea-U.S. interaction over the TPP and U.S.-South Korean
economic relations, see “Economic Relations,” below.)
In March 2015, South Korea announced it was applying to join the Asian Infrastructure
Investment Bank (AIIB). The AIIB is a new China-led multilateral development bank consisting
of over 50 countries.17 This move was reportedly done over the objections of the Obama

Administration. The AIIB has generated considerable controversy. Many analysts say it will help
Asian countries meet their massive infrastructure investment needs. However, many analysts and

United States and others to improve governance and environmental and social standards.
Nuclear Energy Cooperation Agreement
The United States and the Republic of Korea have concluded negotiations on the text of a new
civilian nuclear cooperation agreement, known as a “123 agreement.” Currently, such cooperation
is proceeding under an April 2013 deal that extended the existing agreement, which was due to
expire, for two years.18 Legislation to authorize the two-year extension was passed unanimously
by both the House and Senate and signed into law by President Obama on February 12, 2014
(P.L. 113-81).19
The two governments initialed the text of the agreement in April 2015.20 It is likely they will
formally sign the agreement in June. The U.S. interagency process must also prepare
nonproliferation and national security assessments before submitting it to Congress. The
agreement would need to be transmitted to Congress for review by fall 2015 in order to meet the
required 90 days of continuous session before the two-year extension expires.
For years, talks between South Korea and the United States were not able to resolve disagreement
over how to treat fuel-making technologies in a renewed accord, and therefore the two countries
decided to allow for more negotiating time. The two-year extension was considered a temporary
solution to avoid any disruption to nuclear trade. Since 2013, the two countries have been
negotiating a new agreement, which would be subject to congressional review.
An agreement would not require a positive vote of approval from Congress. Therefore, the
agreement could enter into force after a 30-day consultation period and a review period of 60
days of continuous session21 unless Congress enacted a joint resolution of disapproval. Congress
also has the option of adopting either a joint resolution of approval with (or without) conditions,
or stand-alone legislation that could approve or disapprove the agreement. Any congressional
efforts to block the agreement would be subject to presidential veto.
One point of disagreement in the renewal process has been whether South Korea will press the
United States to include a provision that would allow for the reprocessing of its spent fuel. The
current U.S.-Korea nuclear cooperation agreement, as with other standard agreements,22 requires

U.S. permission before South Korea can reprocess U.S.-origin spent fuel, including spent fuel
from South Korea’s U.S.-designed reactors.23 The issue has become a sensitive one for many
South Korean officials and politicians, who see it as a matter of national sovereignty. The United
States has been reluctant to grant such advance permission due to concerns over the impact on
negotiations with North Korea and on the nonproliferation regime overall. Through reprocessing,
spent fuel can be used to make reactor fuel or to acquire plutonium for weapons. For many years,
the United States and South Korea have worked on joint research and development projects to
address spent fuel disposition, including joint research on pyro-processing, a type of spent fuel
reprocessing. In October 2010, the two countries began a 10-year, three-part joint research project
on pyro-processing that includes joint research and development at Idaho National Laboratory,
development of international safeguards for this technology, economic viability studies, and other
advanced nuclear research including alternatives to pyro-processing for spent fuel disposal.24
According to press reports, the two sides resolved this issue by including provisions in the
renewal agreement text to allow for continuation of the joint research and development of this
technology, as well as the creation of a high-level commission which may periodically review
fuel cycle policy. (For more on the negotiations and the debate over U.S.-ROK civilian nuclear
cooperation, see “Nuclear Energy and Non-Proliferation Cooperation,” below.)
State of the Alliance
Since 2009, the United States and South Korea have accelerated steps to transform their alliance,
broadening it from its primary purpose of defending against a North Korean attack to a regional
and even global partnership. South Korea has contributed troops, equipment, and other assistance
to international missions such as anti-piracy efforts in the Gulf of Aden, the campaign to combat
the spread of Ebola, and reconstruction activities in Afghanistan. Joint statements issued from a
series of high-level meetings emphasized the commitment to modernize and expand the alliance
while reaffirming the maintenance of current level of 28,500 U.S. troops on the peninsula and the
U.S. security guarantee to protect South Korea. Spurred by violent attacks from North Korea in
2010, the alliance partners agreed on a “Counter-Provocation Plan” and then sharpened the
agreement by developing a “Tailored Deterrence Strategy against North Korean Nuclear and
Other WMD Threats.” A high-level joint statement in October 2014 reaffirmed existing efforts
and singled out new cooperative initiatives on cyber, space, and nuclear safety.25
Despite these indicators of strength, the alliance faces a host of challenges in the months and
years ahead. The political atmospherics of the alliance have been positive, but the conservative
Park and Lee governments have slowed the defense budget increases planned under the earlier,
progressive Roh Moo-hyun Administration (2003-2008). The two countries also face disputes
related to the realignment of U.S. forces within Korea, a process that Congress has followed
closely because of concerns about the cost. As the alliance becomes more balanced, Seoul is
wrestling with the tension between developing its own indigenous capabilities and relying on

procurement of U.S. weapons systems. Externally, South Korea also faces China’s strong
resistance to U.S.-South Korea alliance upgrades, particularly those that extend beyond the
Korean Peninsula. The debate in South Korea over ballistic missile defense upgrades is closely
tied to these two issues.
The United States and South Korea have twice delayed their 2007 agreement to transfer wartime
operational control (Opcon) from U.S. to ROK forces. These postponements could be interpreted
as a flexible adjustment to changed circumstances on the Korean Peninsula or as emblematic of
problems with following through on difficult alliance decisions. Although scheduled to be
completed in 2015, the two sides announced in October 2014 that the transfer would occur
according to a “conditions-based approach,” likely no sooner than 2020. The planned realignment
of all U.S. forces from bases near the de-militarized zone (DMZ) border with North Korea to
bases farther south is making progress, but concerns over cost-sharing and configuration of
relocated troops remain. (For more on alliance issues, including congressional actions, see
“Security Relations and the U.S.-ROK Alliance,” below.)
Park Geun-hye’s Political Standing
Park’s public approval ratings were in the 60%-70% range for much of 2013, in part due to
positive assessments of her handling of foreign affairs, particularly inter-Korean relations.
However, by early 2015 her popularity had fallen to near 30% according to some polls. They rose
back to the 40%-45% level following her Saenuri Party’s success in several April 2015 byelections before falling following the MERS outbreak in May and June 2015.
Sentiments toward Park’s government first dropped sharply following the April 2014 sinking of
the Sewol ferry in the waters off the country’s the western coast. The deaths of nearly 300
passengers—mostly high school students—for months cast a pall over South Korea and over the
Park government. The tragedy’s political impact has been likened to the political effects of the
2005 Hurricane Katrina disaster in the United States.26 The Park government has been criticized
for rescuers’ allegedly slow response to distress calls, and the sinking has prompted South
Koreans to ask questions about how well government agencies have enforced safety regulations,
which the Sewol was found to have violated, about the relationship between government
regulators and the industries they oversee, as well as whether companies put profits ahead of
safety. Several of the Sewol’s ownership group and its crew have been convicted of gross
negligence, including the captain, who fled the ship without attempting to help the passengers.
Park also has been weakened by perceptions that her government has done little to follow through
on her campaign pledges to overcome South Korea’s economic difficulties and strengthen its
social safety net. Due to personal or political scandals, a series of Park’s appointees—including
three successive appointees to be prime minister—withdrew their names before taking office.27
These developments have raised questions about her government’s (and her) competence and
willingness to reach outside her inner circle. Most recently, in spring 2015, a new scandal arose
for Park’s government when a South Korean businessman, who later committed suicide, stated
that he had provided bribes to several former close aides to Park. The then-sitting prime minister

was implicated in the bribery scandal, and he subsequently resigned after only two months in
office. Additionally, the government has struggled against criticism that it mishandled the
mounting evidence that the country’s intelligence service tried to influence the 2012 presidential
election in her favor (though no evidence has surfaced that Park knew of the matter). (For
background, see the “South Korean Politics” section, below.)
South Korean Attitudes Toward the United States and the March
2015 Attack Against the U.S. Ambassador
At a March 5, 2015, breakfast meeting in Seoul, a South Korean man attacked U.S. Ambassador
to South Korea Mark Lippert with a knife, sending the Ambassador to the hospital with deep cuts
on his face, fingers, and wrist. Lippert required surgery, including 80 stitches on his face. South
Korean authorities arrested the attacker, Kim Ki-jong, a left-wing civic group’s director who has
expressed support for pro-North Korean causes and has a history of involvement in anti-U.S. and
anti-Japanese protests.
The incident led to an outpouring of support for Lippert and the U.S.-South Korea alliance. This
is in keeping with the results of opinion polling of South Korean attitudes over the past several
years. In a 2014 Pew Research Center survey, over 80% of South Koreans registered a
“favorable” opinion of the United States, compared to less than 50% in 2003.28 That said, some
displays of support for Lippert by government officials and conservative groups were so effusive
that they appear to have made many other South Koreans feel uncomfortable, an indication of the
sensitivities of many South Koreans when they feel their leaders are catering too much to U.S.
interests. Additionally, some South Koreans have accused the Park government and its
conservative base of exploiting the attack to undermine domestic opposition groups and rally
support for the U.S.-South Korea alliance.29
Background on U.S.-South Korea Relations
Overview
While the U.S.-South Korea relationship is highly complex and multifaceted, five factors
arguably drive the scope and state of relations between the two allies:
•
the challenges posed by North Korea, particularly its weapons of mass
destruction programs and perceptions in Washington and Seoul of whether the
Kim Jong-un regime poses a threat, through its belligerence and/or the risk of its
collapse;
•
the growing desire of South Korean leaders to use the country’s middle power
status to play a larger regional and, more recently, global role;

•
China’s rising influence in Northeast Asia, which has become an increasingly
integral consideration in many aspects of U.S.-South Korea strategic and
economic policymaking;
•
South Korea’s transformation into one of the world’s leading economies—with a
strong export-oriented industrial base—which has led to an expansion in the
number and types of trade disputes and helped drive the two countries’ decision
to sign a free trade agreement; and
•
South Korea’s continued democratization, which has raised the importance of
public opinion in Seoul’s foreign policy.
Additionally, while people-to-people ties generally do not directly affect matters of “high”
politics in bilateral relations, the presence of over 1.2 million Korean Americans and the hundreds
of thousands of trips taken annually between the two countries has helped cement the two
countries together.
Some Members of Congress tend be interested in South Korea-related issues because of bilateral
cooperation over North Korea, a desire to oversee the management of the U.S.-South Korea
alliance, South Korea’s growing importance on various global issues, deep bilateral economic
ties, and the interests of many Korean Americans.
Large majorities of South Koreans say they value the U.S.-ROK alliance and have positive
opinions of the United States. However, many South Koreans are resentful of U.S. influence and
chafe when they feel their leaders offer too many concessions to the United States. South Koreans
also tend to be wary of being drawn into U.S. policies that antagonize China. Although many of
these concerns are widely held in South Korea, they are particularly articulated by Korea’s
progressive groups, who have opposed much of Park’s and Lee’s policy agendas and their
governing styles.
Historical Background
The United States and South Korea have been allies since the United States intervened on the
Korean Peninsula in 1950 and fought to repel a North Korean takeover of South Korea. Over
33,000 U.S. troops were killed and over 100,000 were wounded during the three-year conflict. On
October 1, 1953, a little more than two months after the parties to the conflict signed an armistice
agreement, the United States and South Korea signed a Mutual Defense Treaty, which provides
that if either party is attacked by a third country, the other party will act to meet the common
danger. The United States maintains about 28,500 troops in the ROK to supplement the 650,000strong South Korean armed forces. South Korea deployed troops to support the U.S.-led military
campaign in Vietnam. South Korea subsequently has assisted U.S. deployments in other conflicts,
most recently by deploying over 3,000 troops to play a non-combat role in Iraq and over 300 noncombat troops to Afghanistan.
Beginning in the 1960s, rapid economic growth propelled South Korea into the ranks of the
world’s largest industrialized countries. For nearly two decades, South Korea has been one of the
United States’ largest trading partners. Economic growth, coupled with South Korea’s
transformation in the late 1980s from a dictatorship to a democracy, also has helped transform the
ROK into a mid-level regional power that can influence U.S. policy in Northeast Asia,
particularly the United States’ approach toward North Korea.

North Korea in U.S.-ROK Relations
North Korea Policy Coordination
Dealing with North Korea is the dominant strategic element of the U.S.-South Korean
relationship. South Korea’s growing economic, diplomatic, and military power has given Seoul a
much more direct and prominent role in Washington’s planning and thinking about how to deal
with Pyongyang. One possible indicator of South Korea’s centrality to diplomacy over North
Korea is that no successful round of the Six-Party nuclear talks has taken place when interKorean relations have been poor. Since 2009, the United States and South Korea in effect have
adopted a joint approach to Pyongyang that has four main components:
•
keeping the door open to Six-Party Talks over North Korea’s nuclear program but
refusing to re-start them without a North Korean assurance that it would take
“irreversible steps” to denuclearize;30
•
insisting that Six-Party Talks and/or U.S.-North Korean talks must be preceded
by North-South Korean talks on denuclearization and improvements in NorthSouth Korean relations;
•
gradually attempting to alter China’s strategic assessment of North Korea; and
•
responding to Pyongyang’s provocations by tightening sanctions against North
Korean entities and conducting a series of military exercises.
The two countries’ approach could be described as a passive-aggressive policy that in effect is
focused on containing, rather than rolling back, North Korea’s nuclear activities by gradually
increasing international pressure against North Korea. One drawback is that it has allowed
Pyongyang to control the day-to-day situation, according to some experts. While Washington and
Seoul wait to react to Pyongyang’s moves, the criticism runs, North Korea has continued to
develop its nuclear and missile programs and has embarked on a propaganda offensive designed
to shape the eventual negotiating agenda to its benefit. Many of Park’s proposed initiatives with
North Korea appear designed to rectify these perceived shortcomings. To date, however, North
Korea’s general refusal to accept Park’s overtures has not provided her government with an
opportunity to apply her policies.
The joint U.S.-ROK approach has involved elements of both engagement and pressure.
Washington and Seoul have tended to reach out to North Korea during relatively quiescent
periods. In contrast, they have tended to emphasize pressure tactics during times of increased
tension with North Korea. These periods of tension occurred repeatedly after Lee Myung-bak’s
inauguration in February 2008. Most notably, they included North Korean nuclear tests in May
2009 and February 2013; North Korean long-range rocket launches in April 2009, April 2012, and
December 2012; the March 2010 sinking of a South Korean naval vessel, the Cheonan; and the
November 2010 North Korean artillery attack on the South Korean island of Yeonpyeong-do.31
30
The Six-Party talks were held among China, Japan, North Korea, Russia, South Korea, and the United States
between 2003 and 2008.
31
On Yeonpyeong-do, over 150 shells fired by North Korea killed four South Koreans (two Marines and two civilians),
wounded dozens, and destroyed or damaged scores of homes and other buildings. All 46 South Korean sailors on the
Cheonan died. A multinational team that investigated the sinking, led by South Korea, determined that the ship was
sunk by a North Korean submarine. The cause of the Cheonan’s sinking has become highly controversial in South

.
The latter incident was North Korea’s first direct artillery attack on ROK territory since the 19501953 Korean War and served to harden South Korean attitudes toward North Korea. President
Lee reportedly stated that he wanted to order a retaliatory air strike, but the existing rules of
engagement—which he subsequently relaxed—and the existence of the U.S.-ROK military
alliance restrained him.32 After North Korea’s attack on Yeonpeyong-do, many conservative
Koreans criticized as insufficient the Lee government’s military response, which primarily
consisted of launching about 80 shells at North Korea and holding large-scale exercises with the
United States. Park Geun-hye has made boosting deterrence against North Korea a tenet of her
presidency, and has vowed to retaliate if North Korea launches another conventional attack.33
Inter-Korean Relations and Park Geun-Hye’s “Trustpolitik”
Park’s statements on North Korea policy include elements of both conciliation and firmness, and
she has written that her approach would “entail assuming a tough line against North Korea
sometimes and a flexible policy open to negotiations other times.”34 On the one hand, Park has
called for creating a “new era” on the Korean Peninsula by building trust between North and
South Korea. On the other hand, Park also has long stated that a nuclear North Korea “can never
be accepted” and that building trust with Pyongyang will be impossible if it cannot keep the
agreements made with South Korea and the international community. Park also has said that
South Korea will “no longer tolerate” North Korean military attacks, that they will be met with an
“immediate” South Korean response, and that the need for South Korea to punish North Korean
military aggression “must be enforced more vigorously than in the past.”35
The first step in Park’s plan has been attempting to deter North Korea’s provocations by
strengthening South Korea’s defense capabilities, while simultaneously promoting a range of
dialogues and projects with North Korea, generally on a relatively small scale. Among short-term
inter-Korean initiatives, she has proposed that the two Koreas resume a regular dialogue process;
hold regular reunions for families separated since the Korean War ended in 1953; jointly mark the
70th anniversary of their August 1945 liberation from Japanese colonial rule; take steps to link
their rail systems and ports, with an eventual goal of connecting the Korean Peninsula to the
Eurasian continent; and launch assistance programs by South Korea to help North Korean
pregnant mothers and young children, as well as North Korea’s agricultural sector.36
Most of Park’s inter-Korean cooperation initiatives appear to be calibrated to North Korea’s
behavior. For instance, while she generally has de-linked family reunions and some forms of
humanitarian assistance from overall political developments, other steps would apparently require
bigger changes from North Korea. In particular, Park has affirmed that large-scale assistance is
(...continued)
Korea. While most conservatives believe that North Korea was responsible for explosion, many who lean to the left
have criticized the investigation team as biased or argue that its methodology was flawed.

dependent on progress on denuclearization and North Korea refraining from military
provocations.
It is not clear how the Park government will resolve the seeming contradiction between policies
of toughness and flexibility, particularly if North Korea continues to be relatively unresponsive to
her attempts at outreach. A key question will be the extent to which her government will continue
to link progress on denuclearization—the United States’ top concern—to other elements of South
Korea’s approach toward North Korea. Likewise, an issue for the Obama Administration and
Members of Congress is to what extent they will support—or, not oppose—any initiatives by
Park to expand inter-Korean relations.
Deterrence Issues
One factor that may influence U.S.-ROK cooperation on North Korea is Pyongyang’s apparent
progress in its missile and nuclear programs. North Korea’s February 2013 nuclear test, for
instance, triggered calls in South Korea for the United States to redeploy tactical nuclear weapons
in the ROK and for South Korea to develop its own nuclear weapons deterrent. To reassure South
Korea and Japan after North Korea’s test, President Obama personally reaffirmed the U.S.
security guarantee of both countries, including extended deterrence under the United States’ socalled “nuclear umbrella.” In early March 2013, Park stated that “provocations by the North will
be met by stronger counter-responses,” and the chief operations officer at South Korea’s Office of
the Joint Chiefs of Staff was widely quoted as saying that if South Korea is attacked, it will
“forcefully and decisively strike not only the origin of provocation and its supporting forces but
also its command leadership.”37 South Korean defense officials later clarified that “command
leadership” referred to mid-level military commanders who direct violent attacks and not North
Korean political leaders such as Kim Jong-un.
Since North Korea’s 2010 shelling of Yeonpyeong Island, South Korean leaders have shown a
greater willingness to countenance the use of force against North Korea. The Lee government
pushed the alliance to develop a new “proactive deterrence” approach that calls for a more
flexible posture to respond to future attacks, as opposed to the “total war” scenario that drove
much of USFK defense planning in the past. For instance, Lee pushed the United States to relax
restrictions on South Korean ballistic missiles and relaxed the rules of engagement to allow
frontline commanders greater freedom to respond to a North Korean attack without first asking
permission from the military chain of command.38 Such changes have made some analysts and
planners more concerned about the possibility that a small-scale North Korean provocation could
escalate. U.S. defense officials insist that the exceedingly close day-to-day coordination in the
alliance ensures that U.S.-ROK communication would be strong in the event of a new
contingency. The 2013 “Counter-Provocation Plan” was developed to adapt both to the new
threats envisioned from North Korea and to the South Korean government’s new attitudes about
retaliation.

U.S.-South Korea Relations

Security Relations and the U.S.-ROK Alliance
The United States and South Korea are allies under the 1953 Mutual Defense Treaty. Under the
agreement, U.S. military personnel have maintained a continuous presence on the Korean
Peninsula and are committed to help South Korea defend itself, particularly against any
aggression from the North. The United States maintains about 28,500 troops in the ROK. In 2007
and 2008, U.S. commanders in South Korea stated that the future U.S. role in the defense of
South Korea would be mainly an air force and naval role. The ROK armed forces today total
around 650,000 troops, with about 520,000 of them in the Army and around 65,000 each in the
Air Force and Navy. Since 2004, the U.S. Air Force has increased its strength in South Korea
through the regular rotation into South Korea of advanced strike aircraft. These rotations are not a
permanent presence, but the aircraft often remain in South Korea for weeks and sometimes
months for training.
South Korea is included under the U.S. “nuclear umbrella,” also known as “extended deterrence,”
which applies to other non-nuclear U.S. allies as well. A bilateral understanding between
Washington and Seoul gives U.S. forces the “strategic flexibility” to respond to contingencies
outside the peninsula, but under the condition that South Korea would have to consent to their
deployment in an East Asian conflict. In the past, issues surrounding U.S. troop deployments have
been a flashpoint for public disapproval of the military alliance, led by progressive political
groups. But in recent years public support for the alliance has become broader and more resilient
in responding to incidents involving U.S. bases and soldiers in South Korea.
Despite the strengths of the alliance, tensions periodically arise in the partnership. Some of these
involve typical alliance conflicts over burden sharing and cost overruns of ongoing realignment
initiatives. Others reflect sensitive sovereignty issues involving Seoul’s control over its own
military forces and desire to develop its own defense industry without dependence on American
equipment. And although the United States and South Korea share a common interest in repelling
any North Korea attack, views on the overall security landscape in Northeast Asia differ. Seoul
resists adopting positions that threaten or offend China, and often expresses misgivings about
Japan’s efforts to expand its military capabilities.
Upgrades to the Alliance
As mentioned above, since 2009, the two sides have accelerated steps to transform the U.S.-ROK
alliance, broadening it from its primary purpose of defending against a North Korean attack to a
regional and even global partnership. At the same time, deadly provocations from North Korea
have propelled more integrated bilateral planning for responding to possible contingencies. In
2011, the allies adopted a “proactive deterrence” policy to respond swiftly and forcefully to
further provocations. Increasingly advanced joint military exercises have reinforced the enhanced
defense partnership. In March 2013, U.S. officials disclosed that U.S. B-52 and B-2 bombers
participated in exercises held in South Korea, following a period of unusually hostile rhetoric
from Pyongyang.39 The number and pace of high-level meetings have also increased. Since
holding their first ever so-called “2+2” meeting between the U.S. Secretaries of State and Defense
and their South Korean counterparts in 2010, the two sides have held two more 2+2s with an

ever-expanding agenda of cooperative initiatives that includes issues far beyond shared interests
on the Korean Peninsula. These areas include cyber security, space, missile defense, nuclear
safety, climate change, Ebola, and multiple issues in the Middle East. Since 2011, the Korea-U.S.
Integrated Defense Dialogue (KIDD) has held biannual meetings at the Deputy Minister level to
serve as the umbrella framework for multiple U.S.-ROK bilateral initiatives.
Ballistic Missile Defense and Potential THAAD Deployment
As the threat of North Korean ballistic missiles has appeared to intensify in recent years, the
United States and South Korea have examined how to improve their BMD capabilities to defend
South Korea and U.S. forces stationed there. The United States has urged South Korea to develop
advanced BMD capabilities and to integrate them with U.S. and allied BMD systems in the
region. The Vice Chairman of the U.S. Joint Chiefs of Staff stated that a regional missile defense
system would be more effective against North Korean missile launches and would share the
burden of defense among allies.40 However, Washington and Seoul have settled on a policy of
interoperability rather than integration, at least for the short-term. Seoul has been resistant to the
concept of an integrated BMD system for several reasons: the desire, especially strong among
progressive Koreans, for more strategic autonomy; a reluctance to irritate China, which has
consistently voiced opposition to U.S. BMD deployments; and a disinclination to cooperate with
Japan due to poor relations based on disputes over historical and territorial issues.
South Korea is developing its own system, called Korea Air and Missile Defense (KAMD), which
could be compared to the U.S.-produced PAC-2—a second-generation Patriot air defense system.
KAMD will be interoperable with alliance systems and aims to gradually incorporate more
advanced BMD equipment as those elements are procured. The ROK Navy has three destroyers
with Aegis tracking software but no missile interceptors, and the ROK Army fields PAC-2
interceptors. The South Korean military will reportedly purchase U.S. equipment, such as PAC-3
interceptors, SM-2 surface-to-air missiles, and the more advanced SM-6 air defenses starting in
2016. South Korea has also placed a heavy emphasis on indigenous development of hightechnology defense systems and may seek to produce its own BMD equipment.
The potential deployment of one particular BMD system called the Theater High-Altitude Area
Defense (THAAD) system has been controversial in South Korea. Reportedly, the U.S. military is
considering a deployment of a THAAD battery to South Korea to help defend against North
Korean ballistic missiles.41 China has complained that the radar capabilities of the THAAD
system could be configured to allow the United States to monitor airspace deep into Chinese
territory, and in February 2015 the Chinese Minister of Defense lodged a protest with his
counterpart in Seoul.42 Nevertheless, the South Korean Minister of National Defense has praised a
potential U.S. deployment of THAAD, saying it “will be helpful in ... strengthening the security
posture on the peninsula.”43 In one sense, the proposed THAAD deployment has become a litmus
test for Seoul’s straddling the gap between Beijing and Washington. Yet, South Korea has other
concerns surrounding this issue, such as the affordability of buying its own THAAD system from

U.S. Alliance and ROK Defense Reform Plans
Current security developments are taking place in the context of several concurrent defense plans.
The June 2009 Obama-Lee summit produced the “Joint Vision for the Alliance,” which promised
to enhance and globalize future defense cooperation. After the first decision to delay the transfer
of wartime operational control (Opcon) from U.S. to ROK forces, the operational “Strategic
Alliance 2015” roadmap (announced in September 2010) outlined the new Opcon transition
(since delayed until an unspecified date), including a path forward for improvements in ROK
capabilities and changes to U.S. troop relocation. The U.S. military is also undergoing a broad
transformation of its forces in the region; the 8th Army is moving toward becoming a war fighting
headquarters that can deploy to other areas of the world while still serving as a deterrent to any
possible aggression from North Korea.45
Meanwhile, South Korea’s Defense Reform 2020 bill passed by the National Assembly in 2006
laid out a 15-year, 621 trillion won (about $550 million) investment that aimed to reduce the
number of ROK troops while developing a high-tech force and strengthening the Joint Chiefs of
Staff system. The defense reforms announced by the Park Administration in March 2014 aim to
restructure the ground operations command, which will allow the South Korean military to
conduct nimbler operations in response to low-intensity provocations.46 The reforms also plan to
raise the pay of Korean military personnel while reducing the size of the force from the current
655,000 servicemembers to 522,000 by 2022. Despite these changes, the conservative Lee and
Park Administrations have slowed significantly the defense budget increases planned under the
earlier, progressive Roh Moo-hyun Administration (2003-2008).
The Relocation of U.S. Forces Korea (USFK)
The planned realignment of all U.S. forces from bases near the de-militarized zone (DMZ) border
with North Korea to bases farther south is progressing after initial delays, but challenges with
USFK force posture remain. In 2004, Secretary of Defense Donald Rumsfeld authorized a
realignment program to reduce and relocate U.S. forces in South Korea. Under the Rumsfeld
program, the Pentagon withdrew a 3,600-person combat brigade from the Second Division and
sent it to Iraq. The Rumsfeld plan called for the U.S. troop level in South Korea to fall from
37,000 to 25,000 by September 2008. However, in 2008, Secretary of Defense Bob Gates halted
the withdrawals at the level of 28,500. The realignment plan reflects the shift toward a supporting
role for USFK and a desire to resolve the issues arising from the location of the large U.S.
Yongsan base in downtown Seoul.
The USFK base relocation plan has two elements. The first involves the transfer of a large
percentage of the 9,000 U.S. military personnel at the Yongsan base to U.S. Army Garrison
(USAG) Humphreys, which is located near the city of Pyeongtaek some 40 miles south of Seoul.
The second element involves the relocation of about 10,000 troops of the Second Infantry

Division from the demilitarized zone to areas south of the Han River (which runs through Seoul).
The end result would be that USFK sites will decline to 48, from 104 in 2002. The bulk of U.S.
forces will be clustered in the two primary “hubs” of Osan Air Base/USAG Humphreys and
USAG Daegu that contain five “enduring sites” (Osan Air Base, USAG Humphreys, USAG
Daegu, Chinhae Naval Base, and Kunsan Air Base). U.S. counter-fires (counter-artillery) forces
stationed near the DMZ are the exception to this overall relocation. The United States and South
Korea agreed that those U.S. units would not relocate to USAG Humphreys until the South
Korean counter-fires reinforcement plan is completed around the year 2020.47 The city of
Dongducheon, where those soldiers are based, has protested this decision and withdrawn some
cooperation with the U.S. Army.48
The relocations to Pyeongtaek originally were scheduled for completion in 2008, but have been
postponed several times because of the slow construction of new facilities at Pyeongtaek and
South Korean protests of financial difficulties in paying the ROK share of the relocation costs.
The commander of the U.S. Army Corps of Engineers assessed that the entire troop realignment
was 42% complete as of May 2014 and was on track to finish in 2017.49 The original cost
estimate was over $10 billion; South Korea was to contribute $4 billion of this. Estimates in 2010
placed the overall costs at over $13 billion. In congressional testimony in September 2010, U.S.
officials demurred from providing a final figure on the cost of the move, but confirmed that South
Korea would pay more than the original $4 billion.50 U.S. Ambassador Mark Lippert testified to
Congress in June 2014 that the Humphreys Housing Opportunity Program (privately developed
housing for servicemembers and their families inside the base) was a “challenging issue” and that
the Defense Department was re-examining housing plans at USAG Humphreys.51 In summer
2013, USFK broke ground for the new headquarters of the U.S.-Korea Command (KORCOM)
and United Nations Command (UNC) in Pyeongtaek. The facility is to become the command
center for U.S. forces after the planned transfer of wartime operational control.

Tour Normalization
Another complicating factor in the development of the Yongsan Relocation Plan is the
announcement by the Pentagon in 2008 that U.S. military families, for the first time, would be
allowed to join U.S. military personnel in South Korea. Most U.S. troops in South Korea serve
one-year unaccompanied assignments. The goal was to phase out one-year unaccompanied tours
in South Korea, replacing them with 36-month accompanied or 24-month unaccompanied tours.
Supporters of the plan argued that accompanied tours create a more stable force because of
longer, more comfortable tours. If implemented, the “normalization” of tours would increase the
size of the U.S. military community at Osan/Humphries near Pyeongtaek to over 50,000.
In 2011, some Members of Congress raised strong concerns about existing plans to relocate U.S.
bases in South Korea and normalize the tours of U.S. troops there. In May 2011, Senators Carl
Levin, John McCain, and James Webb issued a statement that urged a reconsideration of the
existing plans for U.S. military presence in the Asia Pacific, including the current agreements in
South Korea. A Government Accountability Office (GAO) report released in May 2011 concluded
that the Department of Defense had neither demonstrated a “business case” to justify the tour
normalization initiative, nor considered alternatives.52 In June 2011, the Senate Armed Services
Committee passed amendments to the FY2012 National Defense Authorization Act that prevents
the obligation of any funds for tour normalization until further reviews of the plan are considered
and a complete plan is provided to Congress. The National Defense Authorization Act for Fiscal
Year 2013 (H.R. 4310/P.L. 112-239) includes a provision (Section 2107) that continues to
prohibit funds for tour normalization. Proponents of the existing plans say that such changes
could restrict U.S. military capabilities and readiness as well as jeopardize hard-fought
agreements designed to make the U.S. military presence more politically sustainable in South
Korea.53

For the time being, at least, the Department of Defense (DOD) has “stopped pursuing Tour
Normalization as an initiative for Korea.”54 In January 2013, USFK released a statement saying,
“while improvements to readiness remain the command’s first priority, tour normalization is not
affordable at this time.”55 An April 2013 Senate Armed Services Committee (SASC) report
criticized the policy change as expensive and questioned the legality of how DOD calculated the
housing allowance.56
Cost Sharing
Since 1991, South Korea has provided financial support through a series of Special Measures
Agreements (SMAs) to offset the cost of stationing U.S. forces in Korea. In January 2014, Seoul
and Washington agreed to terms for the next five-year SMA, covering 2014-2018. Under the new
agreement, Seoul will raise its contribution by 6% to 920 billion Korean won ($867 million) in
2014 and then increase its annual payments at the rate of inflation. The new SMA also makes
U.S. use of South Korean funds more transparent than in the past, in response to South Korean
criticism. The ROK Ministry of Defense must approve every contract for which SMA funds are
obligated, and USFK is to submit an annual report on the SMA funds to the National Assembly.
Even with these changes, Korean opposition lawmakers complained that the agreement is
“humiliating” and that USFK might use SMA funds to finance portions of the relocation plan (see
above) in violation of the 2004 agreement.
According to the aforementioned SASC report, U.S. military non-personnel costs in South Korea
totaled about $1.1 billion in 2012, and Korean SMA payments totaled 836 billion won ($765
million). In combination with that sum, other compensation outside the SMA (such as the South
Korea contribution to base relocation) provides for about 40%-45% of the total non-personnel
stationing costs for the U.S. troop presence.57 South Korean SMA payments have not kept pace
with rising U.S. costs. The 2013 SASC report says that between 2008 and 2012 South Korea’s
contributions grew by about $42 million (in line with the pace of inflation), while U.S. nonpersonnel costs increased by more than $500 million.
Opcon Transfer
The United States has agreed to turn over the wartime command of Korean troops to South
Korea, but the two sides have postponed this transfer for several years. Under the current
command arrangement, which is a legacy of U.S. leadership of the U.N. coalition in the 19501953 Korean War, South Korean soldiers would be under the command of U.S. forces if there
were a war on the peninsula. The plan to transfer wartime operational control recognizes South

Korea’s advances in economic and military strength since the Korean War and is seen by many
Koreans as important for South Korean sovereignty. Under a 2007 agreement, the U.S.-ROK
Combined Forces Command (CFC), which has been headed by the U.S. commander in Korea, is
to be replaced with separate U.S. and ROK military commands; the provisional name of the new
U.S. command is Korea Command (KORCOM). When the U.S. and ROK militaries operate as a
combined force under the new command structure, U.S. forces may be under the operational
command of a Korean general officer, but U.S. general officers are to be in charge of U.S.
subcomponents.58 A bilateral Military Cooperation Center would be responsible for planning
military operations, military exercises, logistics support, and intelligence exchanges, and assisting
in the operation of the communication, command, control, and computer systems. It is unclear
what role the U.N. Command, which the USFK Commander also holds, will have in the future
arrangement.
In 2010, the Opcon transfer was postponed to 2015 after a series of provocations from North
Korea and amid concerns about whether South Korean forces were adequately prepared to
assume responsibility. As the new deadline of 2015 grew closer, concerns again emerged about
the timing. Reportedly, South Korean officials worried that their military was not fully prepared
to cope with North Korean threats and that Pyongyang might interpret the Opcon transfer as a
weakening of the alliance’s deterrence.59 Some military experts expressed concern that turning
over control would lead to the United States reducing its overall commitment to South Korean
security.60 In October 2014, the United States and South Korea announced in a joint statement
that the allies would take a “conditions-based approach” to the Opcon transfer and determine the
appropriate timing based on South Korean military capabilities and the security environment on
the Korean Peninsula.61 The decisions to delay the Opcon transfer could be interpreted as a
flexible adjustment to changed circumstances on the Korean Peninsula or as emblematic of
problems with following through on difficult alliance decisions.
In testimony to Congress in April 2015, USFK Commander General Curtis Scaparrotti explained
the three general conditions for Opcon transfer: 62
•
South Korea must develop the command and control capacity to lead a combined
and multinational force in high-intensity conflict,
•
South Korea must improve its capabilities to respond to the growing nuclear and
missile threat in North Korea, and
•
The Opcon transition should take place at a time that is conducive to a transition.
Scaparrotti stated that main areas of attention for improving South Korea’s capabilities will be C4
(command, control, computers, and communication systems), BMD, munitions, and ISR

South Korean Defense Industry and Purchases of U.S. Weapon Systems
South Korea is a major purchaser of U.S. weapon systems and is regularly among the top
customers for Foreign Military Sales (FMS). Although South Korea generally buys the majority
of its weapons from the United States, European and Israeli defense companies also compete for
contracts; Korea is an attractive market because of its rising defense expenditures. According to
Foreign Policy, however, U.S. officials are concerned that South Korea is exploiting U.S. defense
technology in its indigenously produced equipment, some of which is exported to other
countries.64
South Korea will purchase the Lockheed Martin F-35 Joint Strike Fighter to be its next main
fighter aircraft, after the Ministry of Defense in September 2013 threw out the yearlong
acquisition process that selected the Boeing F-15SE fighter.65 The cost of the F-35 had been too
high for the original bid, according to reports, but Korean defense officials determined that only
the F-35 met their requirements for advanced stealth capability. South Korea will purchase 40 F35 fighters at a total cost of $7.83 billion, with the first delivery of aircraft scheduled for 2018.66
South Korea will also purchase four RQ-4 “Global Hawk” unmanned aerial vehicles (UAVs) at a
price of $657 million in total.67 Given concerns that the sale could violate the Missile Technology
Control Regime (MTCR) and non-proliferation norms, observers have called on the Obama
Administration to ensure that the Global Hawks are used strictly for reconnaissance and are not
armed.68 Currently, the South Korean military only operates reconnaissance UAVs, but the
Ministry of National Defense budgeted $447 million to indigenously develop a combat UAV by
2021.69
Korea’s Defense Reform 2020 legislation emphasizes the development of indigenous capabilities
by increasing the percentage of funds allocated to defense research and development (R&D).70
South Korea aims to improve the competitiveness of its defense industry, but problems with the
reliability of certain systems pose a challenge; South Korean firms compete internationally in the
armored vehicle, shipbuilding, and aerospace industries.71 Of particular note is the T-50 Golden
Eagle, a trainer and light fighter aircraft developed jointly by Lockheed Martin and Korea
Aerospace Industries.

The 110th Congress passed legislation that upgraded South Korea’s status as an arms purchaser
from a Major Non-NATO Ally to the NATO Plus Three category (P.L. 110-429), which has
become NATO Plus Five. This upgrade establishes a higher dollar threshold for the requirement
that the U.S. executive branch notify Congress of pending arms sales to South Korea, from $14
million to $25 million. Congress has 15 days to consider the sale and take legislative steps to
block the sale compared to 30 days for Major Non-NATO Allies.
South Korea’s Regional Relations
Looking at their surrounding neighborhood, South Koreans sometimes refer to their country as a
“shrimp among whales.” South Korea’s relations with China and Japan, especially the latter,
combine interdependence and rivalry. Until 2013, trilateral cooperation among the three capitals
generally had been increasing, particularly in the aftermath of the 2008 global financial crisis.
Between 2009 and 2012, leaders of the three countries met annually in standalone summits,
established a trilateral secretariat in Seoul, signed an investment agreement, and laid the
groundwork for trilateral FTA negotiations to begin.72 In 2013, however, tensions between South
Korea and Japan, and between China and Japan, froze much of this burgeoning trilateral
cooperation. One exception was the trilateral FTA negotiations, which were launched in
November 2012 and have continued through mid-2015. The three countries’ foreign ministers met
in March 2015 for the first time in nearly three years, but as of early July 2015 the three countries
have yet to hold a trilateral leaders’ meeting.
Park Geun-hye often speaks of a Northeast Asian “paradox,” in which there is a “disconnect
between growing economic interdependence on the one hand and backward political-security
cooperation on the other.” To resolve this situation, Park has proposed a “Northeast Asian Peace
and Cooperation Initiative” to build trust among Northeast Asian countries and alleviate security
problems through cooperation on non-traditional security issues, such as nuclear safety and the
environment. Critics contend that NAPCI has yet to produce concrete results or define its
objectives clearly.
South Korea-Japan Relations
U.S. policy makers have long encouraged enhanced South Korea-Japan relations. A cooperative
relationship between the two countries, both U.S. treaty allies, and among the three is in U.S.
interests because it arguably enhances regional stability, helps coordination over North Korea
policy, and boosts each country’s ability to deal with the strategic challenges posed by China’s
rise. However, despite increased cooperation, closeness, and interdependence between the South
Korean and Japanese governments, people, and businesses over the past decade, mistrust on
historical and territorial issues continues to linger. South Korea and Japan have competing claims
to the small Dokdo/Takeshima islands in the Sea of Japan (called the East Sea by Koreans), and
most South Koreans complain that Japan has not adequately acknowledged its history of
aggression against Korea.73 For more than three generations beginning in the late 19th century,
Japan intervened directly in Korean affairs, culminating in the annexation of the Korean

From 1999 to 2007, trilateral summits were only held on the sidelines of the Association of Southeast Asian Nations’
“Plus Three” summit (which included the 10 ASEAN countries plus China, Japan, and South Korea).

Since the early 1950s, South Korea has administered Dokdo/Takeshima, which the U.S. government officially calls

peninsula in 1910. Over the next 35 years, Imperial Japan all but attempted to wipe out Korean
culture.74 Among the victims were tens of thousands75 of South Korean “comfort women” who
during the 1930s and 1940s were recruited, many if not most by coercive measures, into
providing sexual services for Japanese soldiers. Whenever South Koreans perceive that Japanese
officials are downplaying or denying this history, it becomes difficult for South Korean leaders to
back initiatives to institutionalize improvements in bilateral ties.
“Comfort Women”-Related Legislation
The U.S. House of Representatives has taken an interest in the comfort women issue. In the 109th Congress, H.Res.
759 was passed by the House International Relations Committee on September 13, 2006, but was not voted on by
the full House. In the 110th Congress, H.Res. 121, with 167 co-sponsors, was passed in the House on July 30, 2007, by
voice vote. This resolution expresses the sense of the House that Japan should “formally acknowledge, apologize, and
accept historical responsibility in a clear and unequivocal manner” for its abuses of the comfort women. The text of
the resolution calls the system “unprecedented in its cruelty” and “one of the largest cases of human trafficking in the
20th century,” asserts that some Japanese textbooks attempt to downplay this and other war crimes, and states that
some Japanese officials have tried to dilute the Kono Statement. In the 113th Congress, the 2014 Consolidated
Appropriations Act (P.L. 113-76, H.R. 3547) indirectly referred to this resolution. P.L. 113-76’s conference committee
issued a Joint Explanatory Statement that called on Federal Agencies to implement directives contained in the July
2013 H.Rept. 113-185, which in turn “urge[d] the Secretary of State to encourage the Government of Japan to
address the issues raised” in H.Res. 121.
From 2008 to 2011, former President Lee Myung-bak sought to separate historical issues from the
larger relationship. In this, he was aided by Japanese leaders from the then-ruling Democratic
Party of Japan (DPJ) who often tended to be more willing to acknowledge Imperial Japan’s
actions against Korea and who placed a priority on improving relations with Seoul. Cemented for
the first time in years by a common strategic outlook on North Korea, trilateral South Korea-U.S.Japan coordination over North Korea policy was particularly close. People-to-people ties
blossomed, with tens of thousands of Japanese and Koreans traveling to the other country every
day. The South Korean and Japanese militaries also stepped up their cooperation, including
holding trilateral exercises with the United States.
However, South Koreans’ interest in forming significant new institutional arrangements with
Japan is dampened by three domestic factors in South Korea. First, continued suspicions of Japan
among the South Korean population place political limitations on how far and how fast Korean
leaders can improve relations. Second, continued disagreements over Dokdo/Takeshima’s
sovereignty continue to weigh down the relationship. Third, unlike Japan, South Korea generally
does not view China as an existential challenge and territorial threat. South Korea also needs
Chinese cooperation on North Korea. Accordingly, South Korean leaders tend to be much more
wary of taking steps that will alarm China. A factor that could change this calculation is if China
is seen as enabling North Korean aggression. Indeed, North Korean acts of provocation are often
followed by breakthroughs in ROK-Japan relations, as well as in ROK-U.S.-Japan cooperation.
All three of these factors contributed to a dramatic downturn in South Korea-Japan relations in
2012. In May and again in June, the two sides were on the verge of signing a completed
intelligence-sharing agreement long sought by the United States as a way to ease trilateral
74
Many Koreans believe that the United States was complicit in this history, by reportedly informally agreeing in a
1905 meeting between U.S. Secretary of War William Taft and Japanese Prime Minister Taro Katsura that the United
States would recognize Japan’s sphere of influence over Korea in return for Japan doing the same for the United States
in the Philippines.

According to some Japanese sources, the number of South Korean comfort women was much lower.

.
cooperation and dialogue. However, a firestorm of criticism against the pact in South Korea led
the Lee government to cancel the signing minutes before it was to take place. Negotiations over a
related deal on exchanging military supplies also broke down. Later that summer, President Lee
made the first-ever visit by a South Korean president to Dokdo/Takeshima. Lee said his visit was
in large measure a response to what he claimed was Japan’s failure to adequately acknowledge
and address the suffering of the World War II comfort women.
Relations worsened after the elections of Park Geun-hye and Abe Shinzo. South Korean leaders
have objected to a series of statements and actions by Abe and his Cabinet officials that many
have interpreted as denying or even glorifying Imperial Japan’s aggression in the early 20th
century. Seoul has maintained that it would have difficulty holding a summit unless Japan adopts
a “correct understanding” of history. Japanese officials counter that their South Korean
counterparts rarely acknowledge the efforts Japan has made to apologize for and address Imperial
Japan’s actions. South Korean attitudes toward Abe degraded after his December 2013 visit to the
Yasukuni Shrine, a Shinto shrine established to “enshrine” the “souls” of Japanese soldiers who
died during war, but that also includes 14 individuals who were convicted as Class A war
criminals after World War II.
Relations deteriorated further in 2014 when the Abe government released a study that examined
the “Kono Statement,” a 1993 apology by then-Chief Cabinet Secretary Yohei Kono that
acknowledged the Japanese military’s role in coercing women into the brothel system. The panel
that conducted the study, carried out in response to a request by a Diet member of a far-right
opposition party, concluded that the statement had been crafted in consultation with Seoul,
implying that the document was not based solely on historical evidence. The Abe government has
pledged that it stands by the Kono Statement, but critics claim that the study discredits the
apology and gives further proof of Tokyo’s (and specifically Abe’s) revisionist aims. South
Korea’s Foreign Ministry called the study “meaningless and unnecessary.”
Neither Park nor Abe appears willing to be seen as compromising with the other. Moreover, the
approaches of both leaders to historical issues appear to contradict one another and are locked in a
vicious circle: Park seeks to bring Japan to a more full-throated acknowledgement and apology
for its pre-WWII actions, and until 2015 appeared to link other aspects of South Korea-Japan
relations to the history issue. Meanwhile, Abe aims to restore Japanese pride in its history by
erasing many signs of what many Japanese nationalists have regarded as self-flagellation, such as
the portrayal of the early 20th century in history textbooks. Given the array of domestic forces
opposed to raising South Korea-Japan relations to a new level, even if the two leaders hold a
formal summit, it is unclear whether the two governments will have the interest or capacity to do
more than maintain ad hoc cooperation, such as in response to aggressive North Korean actions.
South Korea-China Relations
China’s rise influences virtually all aspects of South Korean foreign and economic policy. North
Korea’s growing economic and diplomatic dependence on China since the early 2000s has meant
that South Korea must increasingly factor Beijing’s actions and intentions into its North Korea
policy. China’s influence over North Korea has tended to manifest itself in two ways in Seoul. On
the one hand, most South Korean officials worry that North Korea, particularly its northern
provinces, is drifting into China’s orbit. For those on the political left in South Korea, this was an
argument against Lee’s harder line stance toward inter-Korean relations, which they say has
eroded much of South Korea’s influence over North Korea.
c11173008

25
U.S.-South Korea Relations
.
On the other hand, China’s continued support for North Korea, particularly its perceived backing
of Pyongyang after the Yeonpyeong Island shelling in 2010, has angered many South Koreans,
particularly conservatives. China’s treatment of North Korean refugees, many of whom are
forcibly repatriated to North Korea, has also become a bilateral irritant. Many South Korean
conservatives also express concern that the Chinese have been unwilling to discuss plans for
dealing with various contingencies involving instability in North Korea, though beginning in
2013 there were signs that Beijing had become more willing to engage in these discussions. Park
Geun-hye has called for establishing a trilateral strategic dialogue among Korea, the United
States, and China that presumably could discuss various situations involving North Korea.76
Since China’s 2001 entry into the World Trade Organization, China has emerged as South Korea’s
most important economic partner. Over 20% of South Korea’s total trade is with China, twice the
level for South Korea-U.S. and South Korea-Japan trade.77 For years, China has been the number
one location for South Korean firms’ foreign direct investment, and South Korea is negotiating a
bilateral FTA with China. Yet, even as China is an important source of South Korean economic
growth, it also looms large as an economic competitor. Indeed, fears of increased competition
with Chinese enterprises have been an important motivator for South Korea’s push to negotiate a
series of FTAs with other major trading partners around the globe.
Park Geun-hye has placed a priority on improving South Korea’s relations with China, which
generally are thought to have been cool during Lee Myung-bak’s tenure. In June 2013, Park
traveled to China for what was generally regarded as a successful visit that included meetings
with Chinese President Xi Jinping. Since then, the two sides have expanded a number of highlevel arrangements designed to boost strategic communication and dialogue. As President, Park
has held five meetings with Chinese President Xi Jinping, including a summit in Seoul in July
2014. Notably, Xi’s first visit to the Korean Peninsula as President was to South Korea, not to
China’s ally, North Korea. For China, the summit was an opportunity to reinforce mutual distrust
of Japan, deepen bilateral trade ties, and put pressure on North Korea, whose nuclear weapons
program and other provocations China sees as providing unwelcome justification for the U.S.
military presence in Asia. For South Korea, trade was a key interest, but a more significant aspect
may be the goal of aligning China’s strategic interests with South Korea rather than North Korea.
Although Xi and Park have described bilateral ties as having reached an “unprecedented level of
strategic understanding,” most analysts do not expect that South Korea will prioritize relations
with China at the expense of the U.S. alliance. Many South Koreans point to fundamental
differences between Seoul’s and Beijing’s interests in North Korea, and increasing rivalry
between Chinese and South Korean firms in recent years has accentuated the economic
competition between the two countries.78

Economic Relations
South Korea and the United States are major economic partners. In 2014, two-way trade between
the two countries totaled $114 billion (see Table 1), making South Korea the United States’ sixthlargest trading partner. For some western states and U.S. sectors, the South Korean market is even
more important. South Korea is far more dependent economically on the United States than the
United States is on South Korea. In 2014, the United States was South Korea’s second-largest
trading partner, second-largest export market, and the third-largest source of imports. In 2013, it
was among South Korea’s largest suppliers of foreign direct investment (FDI).
As South Korea has emerged as a major industrialized economy, and as both countries have
become more integrated with the world economy, economic interdependence has become more
complex and attenuated. In particular, the United States’ economic importance to South Korea has
declined relative to other major powers. In 2003, China for the first time displaced the United
States from its perennial place as South Korea’s number one trading partner. Japan and the 28member European Union each also rival and have at times surpassed the United States as South
Korea’s second-largest trading partner.
South Korea’s export-driven economy and subsequent competition with domestic U.S. producers
in certain products has also led to some trade frictions with the United States. For example,
imports of certain South Korean products—mostly steel or stainless steel items as well as
polyester, chemicals, and washing machines—have been the subject of U.S. antidumping and
countervailing duty investigations. As of May 18, 2015, for instance, antidumping duties were
being collected on 14 South Korean imports and countervailing duties were being assessed on 3
South Korean products.79
The George W. Bush and Roh Moo-hyun Administrations initiated the KORUS FTA negotiations
in 2006 and signed an agreement in June 2007.80 In October 2011, the House and Senate passed
H.R. 3080, the United States-Korea Free Trade Agreement Implementation Act, which was
subsequently signed by President Obama.81 In March 2012, the U.S.-South Korea FTA entered
into force.
Upon the date of implementation of the KORUS FTA, 82% of U.S. tariff lines and 80% of South
Korean tariff lines were tariff free in U.S.-South Korean trade, whereas prior to the KORUS FTA,
38% of U.S. tariff lines and 13% of South Korean tariff lines were duty free. By the 10th year of
the agreement, the figures will rise to an estimated 99% and 98%, respectively, with tariff
elimination occurring in stages and the most sensitive products having the longest phase-out
periods. Non-tariff barriers in goods trade and barriers in services trade and foreign investment
are to be reduced or eliminated under the KORUS FTA.
At the time of this writing, the KORUS FTA had been in force for just over three years; therefore
it is still early to ascertain its overall impact on U.S.-South Korean bilateral trade with some
provisions of the agreement yet to take effect and tariffs on certain products continuing to phase
out. Nevertheless, Table 1 below presents U.S.-South Korea merchandise trade data for selected

South Korea-U.S. Interaction over the Proposed TPP
As mentioned earlier, South Korea in fall 2013 signaled its “interest” in joining the TPP negotiations, a move that the
Obama Administration welcomed. The next formal step for South Korea to enter the TPP would be for the South
Korean government to formally announce that it is seeking to participate. The timing of that announcement could
alter what procedures follow. To date, joining the TPP negotiations has required reaching agreement with the existing
negotiating parties over terms of entry, followed by a formal invitation to the negotiations from those members.
Under U.S. trade promotion authority (TPA)—currently expired but still adhered to by the Administration—this
invitation initiates U.S. domestic notification procedures, including notification to Congress of the Administration’s
intent to enter FTA negotiations after a period of 90 days. If South Korea waits until after the TPP agreement is
concluded to announce its intent to join, it would presumably follow the accession procedures that may be set forth
in a final agreement. It is not yet clear what those procedures will be, but the accession process used for the World
Trade Organization (WTO)—countries agree to the established rules of the agreement and then negotiate market
access commitments (tariffs and quotas)—may serve as a template.
As part of these procedures the United States may require some preliminary commitments from Seoul before it

agrees to South Korea’s participation in the negotiations. South Korea’s willingness and ability to resolve ongoing
issues with the implementation of the KORUS FTA are among such measures.82 For example, some U.S. stakeholders
are concerned that proposed auto emissions regulations based on average emissions across a company’s fleet may
unfairly discriminate against U.S. exports, as U.S. auto makers are most competitive in sales of larger vehicles in the
Korean market. Additional concerns have been raised over the Korean government’s implementation of KORUS FTA
commitments on data flows and pharmaceutical intellectual property protection. Both governments are reportedly
working to resolve these issues. U.S. officials reportedly also have been discussing with South Korea issues that would
be included in the TPP but are not part of the KORUS FTA, such as state-owned enterprises and regulatory
coherence, to see if South Korea would be prepared to make commitments in these areas.
Ultimately, Congress must approve implementing legislation if a completed TPP agreement—with or without South
Korea—is to apply to the United States. Additionally, during the TPP negotiating process, Congress has a formal and
informal role in influencing U.S. negotiating positions, including through setting U.S. trade negotiating objectives and
ongoing consultation mechanisms that have been part of TPA. TPA, which expired in 2007, is the authority that
Congress gives to the President to negotiate trade agreements that would receive expedited legislative
consideration.83 In the 113th Congress, legislation to renew TPA was introduced in the House (H.R. 3830) and Senate
(S. 1900), but was never considered. High on the legislative agenda for some Members of Congress and the
Administration, TPA legislation has been introduced in the 114th Congress (H.R. 1890/S. 995), passed by the Senate,
and is expected to be considered in the House in June 2015.
South Korea’s Economic Performance
South Korea was hit hard by the global financial crisis that began in late 2008, because of its
heavy reliance on international trade and its banks’ heavy borrowing from abroad. Real GDP
growth declined to 0.7% in 2009. However, the South Korean economy roared back and grew by
6.5% in 2010. The government took strong countermeasures to blunt the crisis’s impact, engaging
in a series of fiscal stimulus actions worth about 6% of the country’s 2008 GDP, by some
measures the largest such package in the Organization for Economic Cooperation and
Development (OECD) group of industrialized countries. The Bank of Korea (BOK) also acted
aggressively, lowering interest rates from over 5% to 2%—at that time, a record low for South
Korea—and engaging in a range of other operations, estimated by the OECD to be worth over
2.5% of GDP, designed to infuse liquidity in the Korean economy. The BOK negotiated currency
swap agreements with the United States, Japan, and China.84
The South Korean won, after depreciating to around 1,500 won/dollar—a fall of nearly one-third
from early 2008 to early 2009—gradually strengthened against the dollar, oscillating between the
1,000-1,200 won/dollar range since late 2010. The won’s depreciation in 2008 and 2009 helped to
stimulate South Korea’s economic recovery by making its exports cheaper relative to many other
currencies, particularly the Japanese yen. In contrast, since 2013, the yen has depreciated
considerably, falling by a third against the dollar, coinciding with Prime Minister Abe Shinzo’s
election in Japan and his focus on stimulating the Japanese economy with a combination of
monetary, fiscal, and structural reform policies known as “Abenomics.” The yen’s fall has given a

remarks, President Obama said, “I discussed this [KORUS implementation] with President Park last night. We both
agreed that these are issues we can work through together. And given South Korea’s interest in the Trans-Pacific
Partnership, fully implementing KORUS also is the single most important step that South Korea can take now to show
that it’s prepared to eventually meet the high standards of TPP.”

boost to Japanese exporters and proven politically unpopular with trade partners including the
United States and South Korea. President Park criticized the yen’s fall at the November 2014
summit of G-20 leaders.85
Since 2010, South Korean real GDP growth has slowed, in part due to a slowdown in its foreign
trade and the won’s appreciation. South Korea’s economy is highly dependent upon capital
inflows and exports, the latter of which are equal to around half of the country’s annual GDP.
Thus, South Korea remains vulnerable to a slowdown in its major export markets: China, the
United States, the European Union, and Japan. GDP growth in 2011 was 3.7%, 2.3% in 2012,
2.9% in 2013, and 3.3% in 2014. To stimulate growth, the Park government in July 2014
announced a $40 billion stimulus package, equivalent to roughly 3% the size of the South Korean
economy. In March 2015, the Bank of Korea cut South Korea’s base interest rate to a record-low
1.75%. Three months later, the Bank cut the rate again, to 1.5%, citing declining exports and the
contractionary effects of the MERS outbreak on South Korea’s domestic consumption.86

Although South Korea’s economic performance may look favorable to many around the world,
complaints in South Korea have risen in recent years that only rich individuals and large
conglomerates (called chaebol)—which dominate the economy—have benefitted from the
country’s growth since the 2008-2009 slowdown. The 2012 presidential election was largely
fought over the issues of governance (in the wake of a number of corruption scandals), social
welfare, and rising income inequality. Leading figures in both parties, including President Park,
have proposed ways to expand South Korea’s social safety net. As mentioned in the politics
section below, lower-than-expected growth in 2013 and 2014 contributed to Park’s scaling back
her plans. South Korea has one of the lowest rates of social welfare spending in the industrialized
world, a problem exacerbated by the already high levels of indebtedness of the average South

Korean household. The rapid aging of the South Korean population is expected to create
additional financial pressures on government expenditures in the future.
Nuclear Energy and Non-Proliferation Cooperation
Bilateral Nuclear Energy Cooperation
The United States and South Korea have cooperated in the peaceful use of nuclear energy for
over 50 years.87 This cooperation includes commercial projects as well as R&D work on safety,
safeguards, advanced nuclear reactors, and fuel cycle technologies. As mentioned in the
introductory section of this report, in March 2014, the two countries extended for two years their
bilateral civilian nuclear cooperation agreement, often referred to as a “123 agreement” under
section 123 of the Atomic Energy Act (AEA) as amended.88 An extension of the agreement until
March 2016 was approved by Congress (S. 1901) in January 2014 and passed into law (P.L. 11381).
Renewing the agreement is necessary because the existing agreement was concluded before the
current requirements under Section 123a of the AEA were enacted, and the existing agreement
does not meet all of the AEA’s requirements. The agreement is expected to be transmitted to
Congress for review by fall 2015 in order to meet the required 90 days of congressional
consideration. The renewal agreement text was initialed by the two countries in April 2015, and is
expected to be signed in June 2015 to allow for the required review periods. U.S. interagency
officials must review the agreement and prepare required nonproliferation and national security
assessments before submitting it to Congress for the required review period. The agreement
would likely meet all the terms of the Atomic Energy Act89 and not require any exemptions from
the law’s requirements. Therefore, the agreement could enter into force after a 30-day
consultation period and a review period of 60 days of continuous session90 unless Congress
enacted a joint resolution of disapproval. Congress also has the option of adopting either a joint
resolution of approval with (or without) conditions, or stand-alone legislation that could approve
or disapprove the agreement. Any congressional efforts to block the agreement would be subject
to presidential veto.
One of the reasons Seoul and Washington decided on a two-year extension was to give more time
to negotiators to work out a sticking point in the talks—how to treat fuel cycle issues. South
Korea reportedly had requested that the new agreement include a provision that would give
permission in advance for U.S.-obligated spent nuclear fuel to be reprocessed to make new fuel

using a type of reprocessing called pyroprocessing.91 The United States and South Korea are
jointly researching pyroprocessing, but the technology is at the research and development stage.92
The Obama Administration would prefer to conclude the U.S.-ROK joint study on this
technology before making any decision to approve such activities. Reprocessing of U.S.-obligated
spent fuel requires approval by the United States, typically on a case-by-case basis (referred to as
“programmatic consent”). While details are not yet known, press reports indicate that the two
sides have come to an agreement about the extent of research and development of the technology
allowed in South Korea under the new accord. It is expected that the renewed agreement may
contain some additional allowances for R&D in South Korea on pyroprocessing but would not
allow for advanced work without further permission.93 It also provides for a new High Level
Commission where the two sides would review cooperation under the agreement and possibly
resolve fuel cycle issues in the future.
For several decades, the United States has pursued a policy of limiting the spread of enrichment
and reprocessing technology to new states as part of its nonproliferation policies.94 This is
because enrichment and reprocessing can create new fuel or material for nuclear weapons.
Advance permission to reprocess rarely has been included in U.S. nuclear cooperation
agreements, and to date has only been granted to countries that already had the technology (such
as to India, Japan, and Western Europe). However, the issue has become a sensitive one in the
U.S.-ROK relationship. Many South Korean officials and politicians see the United States’ rules
as limiting South Korea’s national sovereignty by requiring U.S. permission for civilian nuclear
activities. This creates a dilemma for U.S. policy as the Obama Administration has been a strong
advocate of limiting the spread of fuel cycle facilities to new states, and would prefer multilateral
solutions to spent fuel disposal.
Spent fuel disposal is a key policy issue for South Korean officials, and some see pyroprocessing
as a potential solution. While South Korean reactor-site spent fuel pools are filling up, the
construction of new spent fuel storage facilities is highly unpopular with the public. Some
officials argue that in order to secure public approval for an interim storage site, the government
needs to provide a long-term plan for the spent fuel. However, some experts point out that byproducts of spent fuel reprocessing would still require long-term storage and disposal options.
Other proponents of pyroprocessing see it as a way to advance energy independence for South
Korea.
For decades, the United States and South Korea have worked on joint research and development
projects to address spent fuel. In the 1990s, the two countries worked intensely on research and
development on a different fuel recycling technology (the “DUPIC” process), but this technology

http://armscontrol.org/act/2012_09/Sout-Korea-US-at-Odds-Over-Nuclear-Pact. Under the 1978 Nuclear
Nonproliferation Act, consent rights apply to material originating in the U.S. or material that has been fabricated into
fuel or irradiated in a reactor with U.S. technology. The majority of South Korea’s spent fuel would need U.S. consent
before it could be reprocessed.
92
Reprocessing of spent nuclear fuel can be used to make new reactor fuel or to separate out plutonium in the spent
fuel for weapons use. Pyroprocessing, or electro-refining, is a non-aqueous method of recycling spent fuel into new fuel
for fast reactors. It only partially separates plutonium and uranium from spent fuel. There is debate over the
proliferation implications of this technology.

ultimately was not commercialized. In the past 10 years, joint research has centered on
pyroprocessing. The Korean Atomic Energy Research Institute (KAERI) is conducting a
laboratory-scale research program on reprocessing spent fuel with an advanced pyroprocessing
technique. U.S.-South Korean bilateral research on pyroprocessing began in 2002 under the
Department of Energy’s International Nuclear Energy Research Initiative (I-NERI). R&D work
on pyroprocessing was temporarily halted by the United States in 2008, due to the proliferation
sensitivity of the technology. In an attempt to find common ground and continue bilateral
research, in October 2010 the United States and South Korea began a 10-year Joint Fuel Cycle
Study on the economics, technical feasibility, and nonproliferation implications of spent fuel
disposition, including pyroprocessing. In July 2013, a new agreement on R&D technology
transfer for joint pyroprocessing work in the United States took effect as part of the Joint Fuel
Cycle Study.95
While some in the Korean nuclear research community have argued for development of
pyroprocessing technology, the level of consensus over the pyroprocessing option among Korean
government agencies, private sector/electric utilities, and the public remains uncertain. Generally,
there appears to be support in South Korea for research and development, but some analysts are
concerned about the economic and technical viability of commercializing the technology. While
the R&D phase would be paid for by the government, the private sector would bear the costs of
commercialization. At a political level, pyroprocessing may have more popularity as a symbol of
South Korean technical advancement and the possibility of energy independence. However, other
public voices are concerned about safety issues related to nuclear energy as a whole. Others see
fuel cycle capabilities as part of a long-term nuclear reactor export strategy, envisioning that
South Korea could have the independent ability to provide fuel and take back waste from new
nuclear power countries in order to increase its competitive edge when seeking power plant
export contracts.
Some analysts critical of the development of pyroprocessing in South Korea point to the 1992
Joint Declaration, in which North and South Korea agreed they would not “possess nuclear
reprocessing and uranium enrichment facilities” and are concerned about the impact of South
Korea’s pyroprocessing on negotiations with the North. Others emphasize that granting
permission for pyroprocessing in South Korea would contradict U.S. nonproliferation policy to
halt the spread of sensitive technologies to new states. Some observers, particularly in South
Korea, point out that the United States has given India and Japan consent to reprocess, and argue
that they should be allowed to develop this technology under safeguards.
Since the technology has not been commercialized anywhere in the world, the United States and
the International Atomic Energy Agency (IAEA) are working with the South Korean government
to develop appropriate IAEA safeguards should the technology be developed further. Whether
pyroprocessing technology can be sufficiently monitored to detect diversion to a weapons
program is a key aspect of the Joint Study.
South Korean Nonproliferation Policy
South Korea has been a consistent and vocal supporter of strengthening the global
nonproliferation regime, which is a set of treaties, voluntary export control arrangements, and
other policy coordination mechanisms that work to prevent the spread of nuclear, biological, and

chemical weapons and their delivery systems. South Korea destroyed all of its chemical weapons
stocks by 2008, under the Chemical Weapons Convention.96 South Korea is a member of the
Nuclear Suppliers’ Group (NSG), which controls sensitive nuclear technology trade, and adheres
to all international nonproliferation treaties and export control regimes. South Korea also
participates in the G-8 Global Partnership, and other U.S.-led initiatives—the Proliferation
Security Initiative, the International Framework for Nuclear Energy Cooperation (formerly
GNEP), and the Global Initiative to Combat Nuclear Terrorism. South Korea has contributed
funds to the United States’ nuclear smuggling prevention effort, run by the Department of Energy,
and contributed to the Organization for the Prohibition of Chemical Weapons (OPCW) Trust
Fund to support the destruction of Syrian chemical weapons.
South Korea is a member of the Non-Proliferation Treaty (NPT) which requires countries to
conclude a safeguards agreement with the International Atomic Energy Agency (IAEA). An
Additional Protocol (AP) to South Korea’s safeguards agreement entered into force as of
February 2004. The AP gives the IAEA increased monitoring authority over the peaceful use of
nuclear technology. In the process of preparing a more complete declaration of nuclear activities
in the country, the Korean Atomic Energy Research Institute (KAERI) disclosed previously
undeclared experiments in its research laboratories on uranium enrichment in 2000, and on
plutonium extraction in 1982. The IAEA Director General reported on these undeclared activities
to the Board of Governors in September 2004, but the Board did not report them to the U.N.
Security Council. In response, the Korean government reconfirmed its cooperation with the IAEA
and commitment to the peaceful use of nuclear energy, and reorganized the oversight of activities
at KAERI. The experiments reminded the international community of South Korea’s plans for a
plutonium-based nuclear weapons program in the early 1970s under President Park Chung-hee,
the father of the current President Park. At that time, deals to acquire reprocessing and other
facilities were canceled under intense U.S. pressure, and Park Chung-hee eventually abandoned
weapons plans in exchange for U.S. security assurances. The original motivations for obtaining
fuel cycle facilities as well as the undeclared experiments continue to cast a shadow over South
Korea’s long-held pursuit of the full fuel cycle. As a result, since 2004, South Korea has aimed to
improve transparency of its nuclear programs and participate fully in the global nonproliferation
regime. In addition, the 1992 Joint Declaration between North and South Korea says that the
countries “shall not possess nuclear reprocessing and uranium enrichment facilities.” Since North
Korea has openly pursued both of these technologies, an intense debate is underway over whether
South Korea should still be bound by those commitments. Some analysts are concerned that a
denuclearization agreement with North Korea could be jeopardized if South Korea does not
uphold the 1992 agreement.
South Korea hosted the 2012 Nuclear Security Summit, a forum initiated by President Obama
shortly after his inauguration. The South Korean government agreed to host the summit because it
fit into the “Global Korea” concept of international leadership and summitry; it was a chance for
the South Korean nuclear industry to showcase its accomplishments; and the South Korean
government was able to emphasize South Korea’s role as a responsible actor in the nuclear field,
in stark contrast with North Korea. It was also seen as an important symbol of trust between the
U.S. and South Korean Presidents.

South Korean Politics
South Korean politics continue to be dominated by Park Geun-hye (born in 1952) and her
conservative Saenuri (“New Frontier”) Party (NFP), which controls the legislature. Ms. Park was
elected in December 2012, becoming not only South Korea’s first woman president, but also the
first presidential candidate to receive more than half of the vote (she captured 51.6%) since South
Korea ended nearly three decades of authoritarian rule in 1988. She is to serve until February
2018. By law, South Korean presidents serve a single five-year term. Park is the daughter of the
late Park Chung-hee, who ruled South Korea from the time he seized power in a 1961 military
coup until his assassination in 1979.
According to the Asan Institute’s daily polling service, Park’s public approval ratings were in the
60%-70% range for much of 2013, in part due to positive assessments of her handling of foreign
affairs, particularly inter-Korean relations. However, her poll numbers declined to the 50% range
by the end of the year, due to a number of factors, including a perception that her government had
done little to follow through on her campaign pledges to overcome South Korea’s economic
difficulties and strengthen its social safety net; the mounting evidence that the country’s
intelligence service had tried to influence the 2012 presidential election in her favor (though no
evidence has surfaced that Park knew of the matter); and her government’s handling of a railway
strike. In particular, Park’s favorability ratings have fallen among voters under 40, a development
that many expected; in the 2012 election under-40 voters chose Park’s opponent, the Democratic
United Party’s Moon Jae-In, by a wide margin. Likewise, those over 50 overwhelmingly voted
for Park and continue to be her strongest base of support.

A Powerful Executive Branch
Nominally, power in South Korea is shared by the president and the 300-member unicameral
National Assembly. Of these, 246 members represent single-member constituencies. The
remaining 54 are selected on the basis of proportional voting. National Assembly members are
elected to four-year terms. The president and the central bureaucracy continue to be the dominant
forces in South Korean policymaking, as formal and informal limitations prevent the National
Assembly from initiating major pieces of legislation.
Political Parties
Presently, there are two major political parties in South Korea: President Park’s conservative
Saenuri Party (which has been translated as “New Frontier Party” or NFP) and the opposition,
center-left New Politics Alliance for Democracy (NPAD).97 The NFP has controlled the Blue
House (the residence and office of South Korea’s president) and the National Assembly since
2008. (See Figure 4.) U.S. ties have historically been much stronger with South Korea’s
conservative parties.
South Korea’s progressive political parties—now largely consolidated in the NPAD—controlled
the Blue House for 10 years, from 1998 to 2008. For a four-year period, from 2004 to 2008, a
progressive party was the largest political group in in the National Assembly and held a majority
for part of that period. After failing to retake the Blue House or National Assembly in 2012
elections, the progressive camp faced several more years without significant tools of power and
influence within the South Korean polity. In the past, the NPAD’s predecessor parties have
advocated positions that, if adopted, could pose challenges for the Obama Administration’s Korea
policy, including calling for the renegotiation of some provisions of the KORUS FTA, and
adopting a more conciliatory approach to North Korea.
A Short History of South Korean Presidential Changes
For most of the first four decades after the country was founded in 1948, South Korea was ruled by authoritarian
governments. The most important of these was led by President Park’s father, Park Chung-hee, a general who seized
power in a military coup in 1961 and ruled until he was murdered by his intelligence chief in 1979. The elder Park’s
legacy is a controversial one. On the one hand, he orchestrated the industrialization of South Korea that transformed
the country from one of the world’s poorest. On the other hand, he ruled with an iron hand and brutally dealt with
real and perceived opponents, be they opposition politicians, labor activists, or civil society leaders. For instance, in
the early 1970s South Korean government agents twice tried to kill then-opposition leader Kim Dae-jung, who in the
second attempt was saved only by U.S. intervention. The divisions that opened under Park continue to be felt today.
Conservative South Koreans tend to emphasize his economic achievements, while progressives focus on his human
rights abuses.
Ever since the mid-1980s, when widespread anti-government protests forced the country’s military rulers to enact
sweeping democratic reforms, democratic institutions and traditions have deepened in South Korea. In 1997, longtime dissident Kim Dae-jung was elected to the presidency, the first time an opposition party had prevailed in a South
Korean presidential election. In December 2002, Kim was succeeded by a member of his left-of-center party: Roh
Moo-hyun, a self-educated former human rights lawyer who emerged from relative obscurity to defeat establishment
candidates in both the primary and general elections. Roh campaigned on a platform of reform—reform of Korean
politics, economic policymaking, and U.S.-ROK relations. He was elected in part because of his embrace of massive
anti-American protests that ensued after a U.S. military vehicle killed two Korean schoolgirls in 2002. Like Kim Daejung, Roh pursued a “sunshine policy” of largely unconditional engagement with North Korea that clashed with the

harder policy line pursued by the Bush Administration until late 2006. Roh also alarmed U.S. policy makers by
speaking of a desire that South Korea should play a “balancing” role among China, the United States, and Japan in
Northeast Asia. Despite this, under Roh’s tenure, South Korea deployed over 3,000 non-combat troops to Iraq—the
third-largest contingent in the international coalition—and the two sides initiated and signed the KORUS FTA.
In the December 2007 election, former Seoul mayor Lee Myung-bak’s victory restored conservatives to the
presidency. Among other items, Lee was known for ushering in an unprecedented level of cooperation with the
United States over North Korea and for steering South Korea through the worst of the 2008-2009 global financial
crisis. Under the slogan “Global Korea,” he also pursued a policy of expanding South Korea’s participation in and
leadership of various global issues. During the final two years of his presidency, however, Lee’s public approval ratings
fell to the 25%-35% level, driven down by—among other factors—a series of scandals surrounding some of his
associates and family members, and by an increasing concern among more Koreans about widening income disparities
between the wealthy and the rest of society.
